mp-5986: BaTiO3 (tetragonal, P4mm, 99)
User remarks: BaTiO3 is (Cubic) Perovskite structured and crystallizes in the monoclinic Cm space group. The structure is three-dimensional. Ba2+ is bonded to twelve O2- atoms to form BaO12 cuboctahedra that share corners with twelve equivalent BaO12 cuboctahedra, faces with six equivalent BaO12 cuboctahedra, and faces with eight …

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 …
