Ferri-magnetism

Ferri-magnetism

Ferri-magnetism is a phenomenon exhibited by materials such as Ferrites, having parallel but opposite alignment of neighboring atoms. The resulting opposing moments are unequal and the material tends to exhibit a form of weak Ferro-magnetism.

Ferri-magnetic
Ferrimagnetism (Wikipedia)

A ferrimagnetic material is a material that has populations of atoms with opposing magnetic moments, as in antiferromagnetism. For ferrimagnetic materials, 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+).

Ferrimagnetism has often been confused with ferromagnetism. The oldest known magnetic substance, magnetite (Fe3O4), was classified as a ferromagnet before Louis Néel discovered ferrimagnetism in 1948. Since the discovery, numerous uses have been found for ferrimagnetic materials, such as hard drive platters and biomedical applications.
