摘要
本文应用对模型近似方法,对于有晶场和无规场存在的混合自旋系统的临界行为和磁化强度作了详细的计算和分析。
The effects of the random field on temperature of the phase transition, and the magnetization of the mixed spin lsing model have been investigated by the use of the pair model approximation. We find some interesting phenomena resulting from competition between the random field and the crystal field.
