Intra-Atomic Hund's Rule and the Low-Temperature Properties of Nearly Magnetic Dilute Alloys

Abstract

The localized spin fluctuation theory is shown to account for the observed values of the ratio $\xi =\left(\frac{\chi d\gamma }{\mathrm{dc}}\right){\left(\frac{\gamma d\chi }{\mathrm{dc}}\right)}^{-1\mathrm{}}$ in a number of dilute alloys of the AIMn type, when orbital degeneracy and intra-atomic Hund's rule coupling of the impurity are taken into account.
