摘　　要：本文基于Andersons d混合模型和Falicovs d库仑互作用模型 ,利用格林函数方法 ,得到局域态电子占有平均值的自洽方程 ,定量地分析在给定不同的参数下 ,局域态电子占有数平均值和局域磁矩 ,研究了稀磁合金的s d混合效应和sIn this paper, based on the Anderson s d mixing model and the Falicov′s s d Coulomb interacting model for dilute magnetic alloy,we obtained self consistent equations determining the average occupation numbers of Local states by using Green′s function method. We soloved these equations and discussed the average occupation numbers and Local magnetic moments of Local states at different parameters. We also studied the influences of Anderson′s mixing s d effect and Failcov′s s d coulomb effect on thermoelectric power.
