| 摘 要： | 本文提出了一个新模型，其中ｆ电子束缚在费米面附近的一个窄带内，Ｓ－Ｐ－ｄ电子是自由的，考虑了它们之间的杂化和４ｆ电子──声子相互作用以及４ｆ电子和传导电子之间的库仑相互作用。数值计算的结果表明，Ｔ＝ＯＫ时，ｆ电子──声子相互作用对ｆ电子形成局域磁矩具有建设性效应，而传导电子和ｆ电子之间的库仑作用对局域磁矩具有破坏性效应。

| Abstract: | In this paper a new model is suggested in which f electrons are bound in a narrow band near Fermi Lev-el, and s-p-d electrons are free In this case hybridization between them , electron -phonon interaction ,4f conduc- tive,electrons ,and Coulomb interaction among electrons are taken into account.Numerical results show that when T=OK,electron phonon interaction has constructive function for f electrons fo form localized magnetic moment, while the Coulomb interaction between conductive electron and electron has destructive function for the localized magnetic moment. |
