Magnetism and Magnetic Materials
The origin of magnetism lies in the orbital and spin motions of electrons and how the electrons interact with one another. The magnetic behavior of materials can be categorized into the following five major groups:
Dia magnetism is a essential property of all matter, though it is usually very weak. It is due to the non-cooperative conduct of orbiting electrons when exposed to an applied magnetic field. Diamagnetic substances are composed of atoms which have no remaining magnetic moments (ie., all the orbital shells are filled and there are no unpaired electrons). But, when exposed to a field, a negative magnetization is formed and therefore the susceptibility is negative.
Para magnetism materials, some of the irons or atoms in the material have a net magnetic moment due to unpaired electrons in incompletely filled orbitals. One of the significant atoms with unpaired electrons is iron. However, distinct magnetic moments do not interrelate magnetically, and like diamagnetism, the magnetization is zero when field is detached. In the existence of a field, there is now a partial configuration of the atomic magnetic moments in the direction of the field, resultant in a net positive magnetization and positive susceptibility.
Ferromagnetism is the simple mechanism by which some materials form permanent magnets, are attracted to magnets. In physics, distinct types of magnetism are distinguished. Ferromagnetism is the strongest type it is the only one that naturally creates forces strong enough to be felt, and in charge for the common phenomena of magnetism in magnets that happens in everyday life .In ionic compounds, such as oxides, additional complex forms of magnetic ordering can happen as a outcome of the crystal arrangement. One kind of magnetic ordering is called ferrimagnetism.
Materials that display antiferromagnetism, the magnetic moments of atoms , commonly related to the spins of electrons, align in a systematic pattern with neighboring spins directing in opposite directions. This is, like ferromagnetism and ferrimagnetism, a appearance of ordered magnetism. Normally, antiferromagnetic order may exist at appropriately low temperatures, disappearing at and above a certain temperature, the Neel temperature Above the Neel temperature, the material is naturally paramagnetic.
A permanent magnet has a magnetic field .A magnetic field consist of flux lines that produce from the north pole to the south pole and back to the north pole through the magnetic material. Unlike magnetic poles have an attractive force between them but, two like poles repel each other. Once nonmagnetic materials such as paper, glass, wood or plastic are placed in a magnetic field, the lines of force are unchanged. When a magnetic material such as iron is placed in a magnetic field, the flux lines tend to be transformed to pass over the magnetic material. Electricity and magnetism are really consequences of the similar thing. Electromagnetism is a division of physics which contains the study of the electromagnetic force, a type of physical interaction that happens between electrically charged particles. The electromagnetic force usually shows electromagnetic fields, such as magnetic fields, electric fields, and light. The electromagnetic force is one of the four fundamental interactions. The additional three fundamental interactions are the strong interaction, the weak interaction, and gravitation.
Nanomaterials and Nanotechnology
Imagine a world where unique phenomena at the molecular scale can lead to entirely new, innovative, and transformative product designs—all done by utilizing properties of materials at the Nano scale level. Nano scale materials are not new to nature or in science. What is new is the ability to engineer nanomaterial, specifically designed with controlled sizes, shapes and compositions, in addition to driving down costs through the adaptation of new and improved manufacturing technology. Carbon Nano materials are an enabler for technology with seemingly endless potential applications: detecting cancer before it spreads, self-repairing buildings and bridges, filtering water, and powering mobile devices from body heat or movement. Carbon nanotubes are incredibly small and incredibly strong, 100 times stronger than steel at one-sixth of the density and 10,000 times smaller than one human hair. Graphene is a carbon membrane that, at just one atom thick, is stronger than steel and can tolerate of wide temperature and pH ranges.
Materials Science and Engineering
Materials Science is a commended scientific expanding, discipline in recent decades to surround, ceramics, glass, polymers, biomaterials and composite materials. It involves the discovery and design of novel materials. Many of the most pressing scientific problems humans presently face are due to the boundaries of the materials that are available and, as a product; major advances in materials science are likely to affect the upcoming of technology considerably.
Hard and Soft Magnetic Materials
Hard magnetic materials
Hard magnetic materials, strongly repel demagnetization when magnetized They are used, in loudspeakers ,motors, holding devices , and meters , and have cervicitis Hc from some hundred to many thousands of oersteds The majority of permanent magnets are of the ceramic type, followed by the Alnicos and the iron-neodymium ,cobalt-samarium, , iron-chromium-cobalt, and elongated single-domain types in decreasing order of usage. The complete quality of a permanent magnet is characterized by the highest-energy product (BH)m but dependent on the design concerns, high Hc, high residual induction Br and reversibility of permeability may also be regulatory factors.
To know the relation between the resistance to demagnetization, that is, the metallurgical microstructure, and coer-civity, it is essential to understand the mechanisms of magnetization reversal. The two main mechanisms are reversal against a shape anisotropy and reversal through nucleation and progress of reverse magnetic domains across crystal anisotropy. The Alnicos, the iron-chromium-cobalt alloys, and the ESD Lodex alloys are instances of materials of the shape anisotropy structure, whereas the cobalt-samarium alloys, the iron-neodymium-boron, and barium ferrites alloys are examples of the crystal anisotropy-con-trolled materials.
Soft Magnetic Materials
Soft magnetic materials are those materials that are simply magnetized and demagnetized. The categories of applications for soft magnetic materials fall into two main categories AC and DC. In DC applications the material is magnetized in order to execute an operation and then demagnetized at the end of the operation, e.g. an electromagnet on a crane at a scrap yard will be swapped on to attract the scrap steel and then switched off to drop the steel. In AC applications the material will be endlessly cycled from being magnetized in solitary direction to the other, through the period of operation, e.g. a power supply transformer. A high penetrability will be desirable for each form of application but the importance of the other properties varies.
Soft magnetic materials are used for electromagnetic pole-pieces, to increase the fields produced by the magnet. Solenoid switches also depend on soft magnetic materials to activate the switches. Mostly permanent magnet devices will use soft magnetic materials to channel fluidity lines or provide a return path for magnetic fields, e.g. MRI body scanners have huge permanent magnets with a load of soft magnetic material to prevent self-demagnetizing fields that would decrease the field in the gap of the scanner.
Magnetic Data Storage
Data storage is a demanding component of any computer system. Magnetic storage is one of the most inexpensive ways to store huge amounts of data and has been executed using floppy disks ,magnetic tape, and hard disk drives. Computer systems stores data in digital format. One of the most commonly used types of digital data storage is magnetic storage. This denotes to any type of data storage utilizing a magnetized medium. Digital data contains of binary information, which is data in the form of zero and ones. Two types of magnetic polarities, each one used to represent either zero or one. Magnetic storage is a of non-volatile storage. This means that the data is not lost when the storage device is not powered. This is not same as volatile storage, which is naturally used for the main memory of a computer system. Volatile storage needs a constant power supply when a computer system is turned off, the data is lost. Magnetic storage is commonly used because it is comparatively cheap in comparison with other storage technologies. Magnetic storage is read-write, which makes it possible to re-use the storage capacity again and again by deleting older data. The storage capacity is very large, making it attractive for storage very large amounts of data. The main limitation of magnetic storage is that accessing the data can be somewhat slow. As a result, most computer systems use magnetic storage for non-volatile storage of large amounts of data but a different type of storage for system memory, such as read-only memory ,which is much smaller but can be accessed much faster.
Spintronic Effects and Devices
The combination of magnetic materials and impurities into Nano electronic devices allows the use of the electron spin, as well as its charge, for transport information. This new prototype in information processing devices has been called “spintronics” in electronics. Functional spintronic devices includes development of new materials and integration of varied materials with atomic-level control. Magnetic tunnel junctions (MTJs) are perfect spintronic devices. They contain three layers ,a ferromagnetic metal, an insulator, and another ferromagnetic metal. The insulator is only a limited nanometers thick, which is thin sufficient to allow tunneling of electrons from one metallic electrode to the another. When the magnetizations of the ferromagnetic layers are allied, the tunneling current is huge and the device resistance is little. When the magnetizations of the ferromagnetic layers are anti-aligned, the tunneling current is slight and the device resistance is huge. If the magnetization of single electrode is fixed, for example by exchange coupling to a neighboring antiferromagnetic, and the other layer can switch dependent on an practical magnetic field, the MTJ display magneto resistance, in which the resistance state of the device depends on the sign of the applied field. MTJs are used as sensors in the read heads of magnetic hard disk drives.
Superconductivity and Superfluidity
Superconductivity is the property of matter when it displays zero resistance to the flow of electric current. Super fluidity is the property of liquid where it acts as a free or zero tension liquid. Together of these phenomenons are reached at actual low temperatures and have challenge in achieving this period. Also succeeding these phenomenons at high temperature is a challenge to researchers and a big of work is going on for this. In spite of this, superconductors are having a wide range of presentations in modern day laboratories and new infrastructures.
Functional Magnetic Materials
Magneto-optic is a type of magnetic materials . A magneto-optic effect is one of the phenomena in which an electromagnetic wave circulates through a medium that has been changed by the presence of a quasistatic magnetic field. such a material, which is also called gyro tropic or gyromagnetic, left and right-rotating elliptical polarizations can spread at different speeds, leading to a number of significant phenomena. When light is transferred through a layer of magneto-optic material, the outcome is called the Faraday effect the plane of polarization can be rotated, forming a Faraday rotator. The outcomes of reflection from a magneto-optic material are recognized as the magneto-optic Kerr effect.
Atomic-level dynamics includes interactions between magnetization Dynamics, electrons, and phonons. These connections are transmissions of energy generally named relaxation. Magnetization damping can occur through energy transfer (relaxation) from an electron's spin to
Itinerant electrons (electron-spin relaxation)
Lattice vibrations (spin-phonon relaxation)
Spin waves, magnons (spin-spin relaxation)
Impurities (spin-electron, spin-phonon, or spin-spin)
Spin waves are circulating disturbances in the ordering of magnetic materials. These low-lying collective excitations happen in magnetic frames with continuous symmetry. From the corresponding quasiparticle point of view, spin waves are recognized as magnons, which are boson modes of the spin lattice that agree roughly to the phonon excitations of the nuclear lattice. As temperature is greater than before, the thermal excitation of spin waves decreases a ferromagnet's spontaneous magnetization. The dynamisms of spin waves are naturally only UeV in keeping with typical Curie points at room temperature.
