本文报道了用中子散射和比热研究稀土单磷化合物晶体场的结果。结果表明，磷化物和其它稀土磷属元素化合物的四阶晶场参数落在一条普适曲线上，该曲线与有效点电荷模型预测的轻稀土的四阶晶场参数接近，但与重稀土的四阶晶场参数明显偏离。
Neutron scattering and specific-heat studies of the crystal fields in the rare-earth monophosphides are reported. It is found that the fourth-order crystal-field parameters for the phosphides and for other rare-earth pnictides fall on a universal curve which is close to that predicted by an effective-point-charge model for the light rare earths but deviates markedly for the heavy rare earths.
