Anisotropy and Crystal Field | SpringerLink

Basic mechanism of magnetocrystalline anisotropy, illustrated by an Sm 3+ ion (blue) in a tetragonal environment (yellow). The Sm spin (arrow) is rigidly coupled to the prolate Hund's-rules 4f charge cloud of the Sm, and the anisotropy energy is equal to the electrostatic interaction energy between the Sm 3+ electrons and the electrostatic …
