Curie temperature is the temperature above which:

Question

Accepted Answer

1. **Temperature Dependence:** The magnetic properties of materials, particularly ferromagnetism, depend on temperature. In ferromagnetic materials, magnetic dipoles are aligned in domains.
2. **Curie Temperature ($T_c$):** As the temperature increases, thermal agitation competes with the domain alignment. At a specific transition temperature known as the Curie temperature, the domain structure disintegrates.
3. **Transition:** Above the Curie temperature, the ferromagnetic material loses its spontaneous magnetization and transforms into a **paramagnetic material**. The susceptibility drops and follows the Curie-Weiss law .
