Explain the following with suitable examples:

Ferrimagnetism

Substances which are slightly attracted in magnetic field and in which domains are grouped in parallel and anti – parallel direction but in unequal number, are called ferromagnetic substances and this property is called as ferromagnetism.

For example, magnetite (Fe³O⁴), ferrite (MgFe²O⁴), ZnFe²O⁴, etc.
