Crystalline anisotropy
WebMar 15, 2024 · Magneto-crystalline anisotropy (MAE) is the energy required per unit volume to change the orientation of the magnetic moments under the external magnetic field, which is required to achieve the high coercivity in the permanent magnets. WebCrystal anisotropy means that easy axis and plane magnetization requires relatively less amount of work; therefore, it is also called magnetocrystalline anisotropy. In non-cubic …
