In magnetism, the Curie–Weiss law describes the magnetic susceptibility χ of a ferromagnet in the paramagnetic region above the Curie temperature: χ = C T − T C {\displaystyle \chi ={\frac {C}{T-T_{\rm {C}}}}} where C is a material-specific Curie constant, T is the absolute temperature, and TC is the Curie temperature, both measured in kelvin. The law predicts a singularity in the susceptibility at T = TC. Below this temperature, the ferromagnet has a spontaneous magnetization.
