摘　　要：采用刘福绥环近似方法，研究ＲＫＫＹ关联对稀磁合金传导电子比热的影响。Based on s-d interaction,we consider RKKY interation in impurity by using ring approximation for s-d interaction ,we express the change of specific heat with RKKY interaction and find that the specific heat of conduction electron in dilute alloy is divergence due to RKKY correlation effect.

关 键 词：环近似 RKKY关联 热力学势 比热
