| 摘 要： | 给出磁性体系的哈密顿量,就可以从体系的拉格朗日运动方程出发,推导出体系自旋的经典运动方程,然后加入耗散项得到自旋动力学模拟的方程,进行迭代体系就能自动走到能量极小值的状态。

| Abstract: | When the Hamiltonian of the magnetic system is given,we can derive the classical motion equations for spin systems from the Lagrangian motion equation,and the equations for simulation of spin dynamics can also be derived by adding the damping term.In the simulation the system will automatically run into the state of minimal energy. |
