【摘要】 采用含长程相互作用以及各向异性能的哈密顿,应用蒙特卡罗方法对二维结构系统在不同参数下的磁结构进行了计算和模拟,发现系统的微观磁结构与长程交换耦合系数密切相关,在不同作用下系统呈现了不同的磁畴结构。更多还原

【Abstract】 Choosing the Hamiltonian with a longrange interaction and the anisot ropy energy,the magnetic structure of the twodimensional systems with different parameters are computed and simulated by using Monte Carlo method.It is found that microscopic magnetic structures of the system are related with the long-ra nge exchange coupling parameter.The system shows different magnetic domains und er different interactions.更多还原
