What is curie temperature?

The temperature at which a ferromagnetic substances losses its ferromagnetism and converted to paramagnetic substances.that temperature is called as curie temperature.

it is fix for every substances but also vary with some ranges.

Fr example in the case of cro2 its curie temperature is  386 kelvin to 393 kelvin..

U can also take an example of gadolinium, its ferrimagnetic at temp below 19 degree celsius..(66 degree farenhit)  approximately room temp. and strongly paramagnetic above that temperature.
