On the Temperature Dependence of Ferro-Magnetic Saturation [PDF]
Proceedings of the National Academy of Sciences, 1933 Accurate data on the saturation intensity of magnetization at low temperatures for monocrystalline materials were recently published by Allen and Constant(1) who, moreover, show that their results fit into the following interesting law: Let the saturation intensity at the temperature T be denoted by MST, the same intensity at the absolute zero of ...
