Question

what is curie temperature of ferromagnetic substance.

Answer 1

Hlo mate

your answer is here,

Below the Curie temperature, the atoms are aligned and parallel, causing spontaneous magnetism; the material is ferromagnetic. Above the Curie temperature the material is paramagnetic, as the atoms lose their ordered magnetic moments when the material undergoes a phase transition.
