Ferrimagnetism, the Glossary

A ferrimagnetic material is a material that has populations of atoms with opposing magnetic moments, as in antiferromagnetism, but these moments are unequal in magnitude, so a spontaneous magnetization remains.^[1]

Absolute zero

Absolute zero is the lowest limit of the thermodynamic temperature scale; a state at which the enthalpy and entropy of a cooled ideal gas reach their minimum value, taken as zero kelvin.

Anisotropy

Anisotropy is the structural property of non-uniformity in different directions, as opposed to isotropy.

Antiferromagnetism

In materials that exhibit antiferromagnetism, the magnetic moments of atoms or molecules, usually related to the spins of electrons, align in a regular pattern with neighboring spins (on different sublattices) pointing in opposite directions. Ferrimagnetism and antiferromagnetism are magnetic ordering and quantum phases.
