不变本征算符法计算各向异性海森伯亚铁磁系统的自旋波能量

The energy of anisotropic Heisenberg ferrimagnetism system in spin waves calculated by invariant eigen-operator method

利用不变本征算符法计算了X-Y-Z模型各向异性海森伯亚铁磁系统的自旋波能量,并讨论了此系统特殊情形下的自旋波能量及不变本征算符法的优点与不足.

The spin waves energy of X-Y-Z model-anisotropic Heisenberg ferrimagnetism system is calculated by the invariant eigen-operator method,and the spin waves energy of such system under especial qualification and advantages or deficiencies of invariant eigen-operator method are discussed.
