What is the term used to describe the phenomenon where ferromagnetic materials lose their magnetic properties completely above a specific characteristic temperature?

💡 Solution & Explanation

The Curie temperature is the temperature above which certain magnetic materials undergo a sharp change in their magnetic properties, becoming paramagnetic instead of ferromagnetic. Alternative terms like Debye temperature are associated with lattice heat capacity in solid-state physics rather than magnetic phase transitions. This physical property is named after the French physicist Pierre Curie who discovered these thermal effects.
