1. Later Tyablikov developed the first consistent quantum theory of magnetic anisotropy . 2. First, their crystalline structures have very high magnetic anisotropy . 3. He created the fusions ferromagnetism theory and developed the theory of magnetic anisotropy . 4. In a real sample the magnetic anisotropy parameter will be different for each particle. 5. This is a form of magnetic anisotropy called " shape anisotropy ". 6. There are several kinds of magnetic anisotropy , the most common of which is magnetocrystalline anisotropy. 7. Magnetic anisotropy is a prerequisite for hysteresis in ferromagnets : without it, a ferromagnet is superparamagnetic.8. "' Magnetic anisotropy "'is the directional dependence of a material's magnetic properties. 9. Among his other interests were the optics of colloids, electrical and magnetic anisotropy , and the physiology of human vision. 10. On the other hand, materials with low magnetic anisotropy usually have low coercivity, their magnetization is easy to change.
