Answer :

Ferromagnetic materials: The materials which possess magnetism in the absence of applied magnetic field is known as ferromagnetic materials.

Ferrimagnetic materials:Ferrimagnetic materials are like ferromagnets in that they hold a spontaneous magnetization below the Curie temperature and show no magnetic order (are paramagnetic) above this temperature.

Answer :

Ferromagnetic materials: The materials which possess magnetism in the absence of applied magnetic field is known as ferromagnetic materials.

Example: iron, nickel, cobalt

Ferrimagnetic materials: They contain magnetic moments aligned antiparallel to one another, similar to antiferromagnetic materials. However, instead of having a zero net magnetic moment, different numbers of unpaired electrons in the component transition metals result do not cancel one another out, resulting in a spontaneous magnetization.

Example: Magnetite, Ferrous ferrite, Nickel ferrite, Manganese ferrite.
