摘要

为了理解铁/反铁交换耦合薄膜，对反铁磁自旋构型进行了蒙特卡罗模拟。通过与散装材料实验数据的比较，验证了模拟的有效性。所计算的有序铁磁层的反铁磁自旋构型显示出在自旋方向上的衰减振荡。然而，与往常一样，计算的边界交换耦合大于估计的实验值。通过在反铁磁区施加弱交错场并去除铁磁层，获得了有效边界交换耦合的合理值。

An Investigation of Exchange-Coupled Films by 0-K Monte Carlo Simulation Using the Classical Heisenberg Model

Monte Carlo simulations of antiferromagnetic spin configurations were performed in order to understand ferro/antiferro-exchange-coupled films. The validity of the simulation was confirmed by comparison with experimental data for bulk materials. The calculated antiferromagnetic spin configurations of the ordered ferromagnetic layer showed decayed oscillation in the spin directions. However, the calculated boundary exchange coupling was larger than the estimated experimental value, as is usual. A reasonable value for the effective boundary exchange coupling was obtained by applying a weak staggered field in the antiferromagnetic region and removing the ferromagnetic layer.
