摘要
用量子理论计算了Er3Ga5O12在[100]和[111]方向的基态磁化强度随温度的变化情况,证实了实验的结论,计算了4I13/2和4I15/2两个多重项耦合对基态磁化强度的影响,进一步从理论上分析了Er3Ga5O12磁性非线性产生的微观机制。
A calculation of temperature dependence of the magnetization of the ground state in Er_3Ga_5O_(12) has been made using quantum theory when the magnetic field was applied paralled to and .The results of calculation were in good agreement with the experimental ones. The influence of the mixing of the ~4I_(13/2) multiplet with the ~4I_(15/2) multiplet on the magnetization of the ground state has also been calculated, that was advantageous to show the further factors on the anisotropy by theory analysis.
