Curie Point

Curie Point / Curie Temperature

There is a critical Temperature called Curie Point, above which the ferro magnetic material lose their magnetic property and to become a paramagnetic material. The curie temperature is named after Pierre curie who showed that magnetism was lost at a particular temperature.

Curie temperature TC, or curie point is the temperature where a material’s permanent magnetism changes to induced magnetism. The force of magnetism is determined by magnetic moments.

Curie Temperature of materials:

MaterialCurie Temperature (K)
Cobalt1400
Nickel631
Silicon iron690 Degree C
Super alloy400 Degree C
Iron1043

Above curie temperature the domain structure tends to disrupt and domain lose their alignment and become arranged in a random fashion, thus the material losses its ferro magnetic property and become paramagnet.
