Critical temperature. Is the state change temperature of materials compounds example like. At that temperature, water changes its state from liquid to vapor or liquid to solid. The material loses its properties or changes in this context it's magnetic materials.

Thank you @Renjith and @Yaswi.

Ferromagnetic materials are materials that have magnetic properties similar to those of iron. Electrons have an intrinsic property, called spin. Because they have spin, they have a magnetic moment, similar to a small current loop.

Curie temperature (Tc) is the maximum temperature at which certain materials losses their permanent magnetic property.
Eg :-
Iron - 1043.
Cobalt. - 1400.
Alnico. - 973-1133.

Please define spontaneous polarization clearly.

Spontaneous polarization is the electrochemical reactions of certain ore bodies causing spontaneous electrical potential. The material is said to be spontaneously polarized when electric field E is zero and polarization P is not zero. (i.e, polarization by its own).
