摘要
本文从电子顺磁共振实验测出的立方零场分裂常数 a 导出了 KM_gF_3:Mn^(2+)和 KZnF_3:Mn^(2+)的晶场参量 D_q,由此计算出了激发态能级,结果与光谱实验符合很好,而用点电荷模型计算出 D_q 要大～10%,光谱的计算值与实验值相差很远.这表明,本文提出的方法是可行的.
The crystal-field parameter D_ is derived from the cubic zero-field splitting constant α measured from electron paramagnetic resonance experiment for Mn^(2+):KMgF_3 and Mn^(2+):KZnF_3 Crystaks.The results used to calculate the excited energy levels and the theoretical values agree satisfactorily with the experimental findings.The point charge model is also used to calculate the D_q-values;the results are about 10% greater than those from α and are bad agreement in comparsion with the experimental results.This shows that the method presented here is available.
