摘要
根据量子理论计算了Er_3Ga_5O_(12)低温时在强磁场作用下的磁化强度,经过定量计算,证明了外磁场沿着[100]和[111]方向时其磁化强度所呈现的复杂的非线性各向异性关系,而顺磁性超交换作用是一个不可忽略的影响因素.
Magnetization of Er3Ga5Oi2 is calculated with quantum theory when temperature is low and magnetic field is strong. By quantitive calculation, magnetization is proved to be complex nonlinear anisotropy when magnetic field is applied to [100] and [111] directions. The study shows that super-exchange interaction is an important factor.
