Question

curie temperatures is the temperature above which

Answer 1

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.

Answer 2

In physics and materials science, the Curie temperature (TC), or Curie point, is the temperature above which magnetic materials lose their ferromagnetic properties, to be replaced by paramagnetism.
