Abstract FORCs (first-order reversal curves) diagrams prove to be an efficient experimental technique to investigate magnetic interactions in complex systems. In experiments, as a rule, it is difficult to relate actual microstructural changes to the evolution of FORCs diagrams. Here, using Molecular Dynamics simulations, we calculate FORCs for two simple models of a magnetic elastomer. The simplicity of these models allows to relate directly both, the rigidity of the matrix and the magnetoelastic coupling to the shape and intensity of FORCs diagrams.

在计算机模拟中测量 FORCs 图作为获得微观洞察力的手段

摘要 FORC（一阶反转曲线）图被证明是研究复杂系统中磁相互作用的有效实验技术。在实验中，通常很难将实际的微观结构变化与 FORC 图表的演变联系起来。在这里，我们使用分子动力学模拟计算了两个简单的磁性弹性体模型的 FORC。这些模型的简单性允许将矩阵的刚度和磁弹性耦合与 FORC 图的形状和强度直接相关。
