| 摘 要： | 在晶场理论和分子场理论的基础上,通过模拟Taiki Ueda和M.S.Kim等人测量的磁化率实验结果,得到了稀土化合物CeRhGe和CeRhSn的晶场分裂,分析了晶场效应对化合物磁性质的影响.计算结果表明,Ce3 晶场分裂得到了双基态,两种化合物的第一激发能和总激发能分别是723 K、610 K和970 K、1130 K,与实验获得了较好的吻合.

| Abstract: | We obtain the crystalline electric field(CEF) schemes of rare earth compound CeRhGe and CeRhSn by means of simulating magnetic susceptibility measured by Ueda and Kim groups,respectively.The CEF analysis suggests that Ce3 has a doublet ground state.The first excited and the total excited energies are estimated to be about 723 K,610 K and 970 K,1130 K,respectively.The CEF schemes have well explained the magnetic anisotropy and are in good agreement with the experimental data. |
