| 摘 要： | 在一些材料中不但铁磁态与超导态共存,而且磁有序性和超导在同一临界参数下会同时出现,为解释以上现象而建立了一个模型,即:局域自旋与导电电子对相互作用模型.利用此模型,通过平均场理论散射矩阵方法得到了弱耦合极限下BCS理论形式Cooper对能量的关系式,及BCS理论中有S波对称序参量的相互作用形式.

| Abstract: | In a few compounds,ferromagnetic order and superconductivity appear to arise at the same value of a critical parameter.In order to explain that we assumed a model based on a coupling of two conduction electrons and one localized spin.With this model,we resolved the problem of electrons Cooper pair under weak ferromagnetic state,and obtained the interaction of S-wave symmetry of the order parameter in BCS theory by mean field T matrix method. |
