| 摘 要： | 考虑最近邻格点 f电子的电荷相关和自旋相关,用局域方法研究了对称 An-derson 晶格中由局域磁矩引起的极化。结果表明,极化总是反铁磁的;当同一格点相反自旋 f 电子间的库仑作用增大或 d-f 电子间杂化强度减小时,这种反铁磁极化变强。

| Abstract: | Taking account of the chargc correlation and spin correlationbetween nearest neighbors,the local approach was used to investigate the po-larization invoked by local moments in symmetric Anderson lattice. The resultsshow that the polarization is always antiferromagnetic. When the Coulomb in-teraction between antispin f-electrons at the same lattice intensifies or thehybridization strength of d-f electrons decreases, the polarization becomesstrong. |
