Crystalline anisotropy
WebJul 7, 2024 · Anisotropy is observed in crystalline solids because the concentration of the atoms is different in different directions of the unit cell. If you look along the X-axis, the concentration of particles around it is different than the distribution of atoms around the y-axis and same is for the z-axis. WebApr 8, 2024 · Magnetocrystalline Anisotropy: It is mainly found in ferromagnetic materials. A ferromagnetic material takes more energy in a specific direction to magnetize. These directions are about the principal axis of the crystalline material. Shape Anisotropy: Anisotropy depends on the shape of the object.
