NEEL: Phase Change in Chromium at the Néel
Temperature
The first-order phase transition of Chromium between antiferromagnetic and paramagnetic states is studied. Antiferromagnetic thin-films are key
components in the multilayer devices in use for magnetic-disk data storage systems. Louis Néel won the Nobel Prize in Physics in 1970 for antiferromagnetism and ferrimagnetism.
(The experiment is currently located in MP239; last write-up revision: January 2018.)
