In the context of materials science & engineering, what is the difference between Curie temperature and Debye temperature? Solution Curie temperature (TC), or Curie point, is the temperature at which certain materials lose theirpermanent magnetic properties, to be replaced by induced magnetism. The Curie temperature is named after Pierre Curie, who showed that magnetism was lost at a critical temperature. Debye temperature is thetemperature of a crystal\'s highest normal mode of vibration, i.e., the highest temperature that can be achieved due to a single normal vibration.
