NEEL: Phase Change in Chromium at the Néel
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.)

take data in this experiment: Neel Temperature.vi (Last updated December

should be in a sub-directory called “Neel LabView Files” is Save Data Files.vi
