摘要
基于单离子晶场模型 ,提出了计算稀土 Fe(Co)金属间化合物取向多晶样品磁化曲线的方法 .用此方法计算了取向Pr2 Fe14 B和Nd2 Fe14 B多晶的高场磁化曲线 ,计算中使用了拟合化合物单晶磁化曲线得到的交换场与晶场参数 .计算曲线与实验曲线相符合 .
On the basis of the single\|ion model, a method of calculation on the magnetization curves for magnetically aligned rare\|earth\|Fe(Co) intermetallic compound is developed. High\|field magnetization curves for magnetically aligned Nd\-2Fe\-\{14\}B and Pr\-2Fe\-\{14\}B were calculated by using the above method. In the calculations, the fitted exchange and crystalline field parameters from magnetization curves of the single crystals were used. The calculated curves agree well with the experiments.
