Curie Temperature vs. Neel Temperature: What's the Difference?

Edited by Sumera Saeed || By Sawaira Riaz || Published on February 1, 2024
Curie temperature is the point at which a ferromagnetic material becomes paramagnetic, while Néel temperature is the temperature at which an antiferromagnetic material becomes paramagnetic.

Key Differences

Curie temperature, named after Pierre Curie, is the critical point where ferromagnetic materials lose their magnetic ordering and become paramagnetic. Néel temperature, named after Louis Néel, refers to the temperature at which antiferromagnetic materials transition to a paramagnetic state.
