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:
Material | Curie Temperature (K) |
Cobalt | 1400 |
Nickel | 631 |
Silicon iron | 690 Degree C |
Super alloy | 400 Degree C |
Iron | 1043 |
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.
