MAE is another important parameter, which defines the hardness with respect to the microscopic characteristics. In spite of the highest uniaxial MAE of ~24.2 MJ/m3 (12.96 meV/f.u.) in SmCo 5, 1 the world market is dominated by the Nd 2Fe 14B (MAE of ~4.9 MJ/m 3) …
Magnetic Anisotropy - an overview ScienceDirect Topics
The magnetocrystalline anisotropy parameters are generally defined for ferromagnets that are constrained to remain undeformed as the direction of magnetization changes. However, coupling between the magnetization and the lattice does result in deformation, an effect called … See more In physics, a ferromagnetic material is said to have magnetocrystalline anisotropy if it takes more energy to magnetize it in certain directions than in others. These directions are usually related to the principal axes of its See more The spin-orbit interaction is the primary source of magnetocrystalline anisotropy. It is basically the orbital motion of the electrons which couples with crystal electric field giving … See more The magnetocrystalline anisotropy energy is generally represented as an expansion in powers of the direction cosines of the magnetization. The … See more • Anisotropy energy See more • Chikazumi, Sōshin (1997). Physics of Ferromagnetism. Clarendon Press. ISBN 0-19-851776-9. • Cullity, B. D.; Graham, C. D. (2008). Introduction … See more Magnetocrystalline anisotropy has a great influence on industrial uses of ferromagnetic materials. Materials with high magnetic anisotropy usually have high coercivity, that is, they are hard to demagnetize. These are called "hard" ferromagnetic … See more The magnetocrystalline anisotropy parameters have a strong dependence on temperature. They generally decrease rapidly as the temperature approaches the Curie temperature, so the crystal becomes effectively isotropic. Some materials also have an isotropic … See more Webanisotropy, in physics, the quality of exhibiting properties with different values when measured along axes in different directions.
