摘要
利用算符的运动方程理论计算了一维更键Heisenberg自旋反铁磁链系统的线性色散关系.并对其色散曲线进行了讨论.在Γ点(k=0的点),又讨论了随各项参数的变化对磁振子能量的影响.
In the paper, relation of dispersion curves of spin antiferromagnetic system is dedaced based on (equation) of motion on operators. And the dispersion curves are discussed.The influence because of each parameter changes on magnon energy is investigated at Γ point (point of k=0).
