Hutchison group,and considering the crystalline electric field(CEF) effect with point-charge model,the paper obtains CEF parameters,CEF splitting levels and the corresponding wave functions of rare earth compound TbNiAl_4.
Hutchison小组测量的磁化率倒数与温度的关系曲线,得到了稀土化合物TbNiAl4的晶场系数、晶场分裂能和相应波函数,并从理论上分析了晶场效应对化合物磁性的影响。
