Ferrimagnetism

Type of magnetic phenomenon

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. This can, for example, occur when the populations consist of different atoms or ions (such as Fe2+ and Fe3+). In addition , ferrimagnets can be compensated Néel-ordered magnets, i.e.
