Define ferrimagnetism with suitable examples.

Answer»

SOLUTION :When magnetic moments are aligned in parallel and anti-parallel directions in unequal NUMBERS resulting in net moment, then the magnetism is CALLED FERRIMAGNETISM. e.g. in `Fe_(3)O_(4), MgFe_(2)O_(4), CuFe_(2)O_(4), ZnFe_(2)O_(4)`, etc.
