概要
- 論文の詳細を見る
A spin glass based on an itinerant electron model is considered. From the spin conservation law, some identities are obtained. By using them, the role of the vertex correction II^<+-> defined as <(x^<+->>)^2>_c=<x^<+->>_c^2II^<+-> is investigated. Here x^<+-> is the transverse spin susceptibility and <・・・>_c means the configuration average. Within a self-consistent single-site approximation, we give a phase diagram in the c-Ux^<+-> plane in terms of a simple model for the spectrum of x^<+-> and illustrate the regions of the spin glass and paramagnetic states.
