The Curie-Weiss law describes the susceptibility in the paramagnetic region above the Curie point:
where
- Χ is the susceptibility
- C is a material-specific Curie constant
- T is absolute temperature, measured in kelvins
- Tc is the Curie temperature, measured in kelvins
The susceptibility has a singularity at T = Tc. At this temperature and below there exists a spontaneous magnetization.
