Explain Ferrimagnetic magnetic materials.

Ferrimagnetic Materials: In such materials unequal magnetic dipoles are lined up anti-parallel to each other. And permeabilities are of the order of ferromagnetic materials under ordinary states the magnetic characteristics of ferromagnetic materials are likewise to those of ferromagnetic materials, like they demonstrate spontaneous magnetization below a temperature, illustration: magnetite and nickel ferrite. The susceptibility of these is specified by χ = C / T ± θ, here C is curie constant and T is temperature.
