| elucidation | Any amorphous structure entails a distribution of nearest-neighbour environments and bond lengths for a given magnetic atom, described by the radial distribution function and higher-order correlation functions. These distributions lead to a distribution of site moments, exchange interactions, dipolar and crystal fields, all of which influence the nature of the magnetic order. |

M(H): Magnetization as function of the internal field. M(H'): Magnetization as function of the external field. J(H): Magnetic polarization as function of the internal field.

| elucidation | Magnetocrystalline anisotropy is an intrinsic property. The magnetisation process is different when the field is applied along different crystallographic directions, and the anisotropy reflects the crystal symmetry. Its origin is in the crystal-field interaction and spin-orbit coupling, or else the interatomic dipole–dipole interaction. |
