摘要
理论计算了高磁场下顺磁性NdF3的磁特性.理论分析表明,顺磁性NdF3的分子场系数υ<0.在高于奈尔温度的一段温度区域内,随着温度的上升,NdF3介质的磁化率χ会发生急剧变化,同时引起磁亚晶格结构异乎寻常的变化.理论与实验结果较为吻合.
The magnetic properties of the paramagnetic neodymium trifluoride NdF3 in high magnetic field were theoretically calculated. According to the theoretical analysis, the molecular field coefficient v of the paramagnetic NdF3 must be less than zero. The magnetic susceptibility χ will acutely change with the increasing of the temperature in a certain region of T〉TN, meanwhile, extraordinary changes of the magnetic sublattice structure happen. There is a good agreement between the theory and experimental results.
