The critical point temperature is the end point of the temperature where the material change into other form.
Ex, when we boil the water, then come one stage where the water change in the vapor this is called critical point temperature.

What is spontaneous polarization? Can anyone explain it?

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).

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

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.
