Preferred name: | 
Curie temperature |

Short name: | 
T_C |

Definition: | 
minimum temperature below which a magnetic material is ferromagnetic or ferrimagnetic and above which it is paramagnetic |

Note: | 
The change of state is not perfectly sharp, so the above definition may not give a value sufficiently defined for practical purposes. To get a more definite value, the graph of the square of the specific saturation magnetisation (i.e. sigma2) as a function of temperature should be extrapolated to sigma2 = 0. The Curie point may then be taken as the point where this extrapolation meets the temperature axis. |
