| 摘 要： | 采用点电荷晶场理论模型,通过对Ce1-xYxPt2Si2(x=0.2,0.55,0.9)磁化率倒数—温度曲线的模拟,得到了其晶场分裂能和相应波函数,计算表明:晶场分裂能随x的增大而减小,晶场作用使得Ce3+六重简并基态分裂得到混合的双基态.

| Abstract: | The research is about the effect of the crystalline electric field(CEF)on the magnetic properties of :Ce1-xYxPt2Si2.The temperature dependence of the inverse magnetic susceptibility is simulated using CEF theory.By simulation,the research has obtained the CEF splitting levels and the corresponding wave functions of :Ce1-xYxPt2Si2.The CEF splitting energies of Ce3+ decrease with the increase of the substitution x.The six fold degeneracy ground state of Ce3+ is splitted into mixed double ground states through crystalline electric field effect. |
