i think u are asking about curie temperature....here is what wikipedia says.....................he Curie temperature of a ferromagnetic or a ferrimagnetic material is the reversible point above which it becomes paramagnetic ...Below the Curie temperature themagnetic moments are aligned parallel within magnetic domains in ferromagnetic materials and anti-parallel in antiferrimagnetic materials. As the temperature is increased towards the Curie point, the alignment (magnetization) within each domain decreases. Above the Curie temperature, the material isparamagnetic so that magnetic moments are in a completely disordered state.

.....................it is named after the great scientist PIERRE CURIE!

The Curie temperature (Tc) is the critical temperature beyond which a previously ferromagnetic material becomes paramagnetic.

On the atomic level, below the Curie temperature the magnetic moments, contributed mainly by the electrons, are alligned in their respective domains and even a weak external field results in a net magnetization.

As the temperature increases to Tc and above however, fluctuations due to the increase in thermal energydestroy that allignment.
