Ferrimagnetic materials are like Paramagnets in that they show no magnetic order above the Neel Temperature , and are like Ferromagnets in that they can hold a spontaneous magnetization below. However, there is sometimes a temperature ''below'' the Neel temperature at which the two sublattices have equal moments, resulting in a net Magnetic Moment of zero; this is called the ''compensation point''. The compensation point is observed easily in Garnet s. Ferrimagnetism is exhibited by ferrites and magnetic garnets. The oldest-known magnetic substance, Magnetite , is a ferrimagnet; it was originally classified as a ferromagnet before Néel 's discovery of ferrimagnetism and antiferromagnetism. SEE ALSO |
