... magnetic moments coming from their electrons. At mK temperatures, the magnetic disorder entropy (about 1 J/mol) is large compared to all other entropies, such as lattice and coduction electron entropies, which may be neglected. We have previously looked at the properties of a paramagnetic salt. The ...
