These directions are usually related to the principal axes of its crystal lattice. It is a special case of magnetic anisotropy. In other words, the excess energy required to magnetize a specimen in a particular direction over that required to magnetize it along the easy direction is called crystalline anisotropy energy. harshad mehta movie ottWebAug 11, 2024 · The magnetocrystalline anisotropy of minerals from these silicate groups will be described in this chapter. 4.1.
