Weak Itinerant Ferromagnetism in Weakly Localized Regime

抄録

The effect of Anderson localization on the weak ferromagnetism has been examined in the weakly localized regime by extending to dirty systems the self-consistent renormalization theory of spin fluctuations developed so far for clean systems. The result indicates that the relative change of the Curie temperature due to disorder can be appreciable for weak ferromagnets with low Curie temperatures.
