论文摘要

外部磁场提供了一种宏观控制机制,以影响多晶材料的微观结构。我们对具有磁性扩展相位晶体(XPFC)模型的薄膜中强磁场对晶粒生长的影响进行建模。磁结构效应被纳入相互空间的相关函数。使用这种方法,可以控制磁性各向异性,并且可以确定与实验结果一致的多种几何和拓扑特性。

External magnetic fields provide a macroscopic control mechanism to influence the microstructure of polycrystalline materials. We model the influence of strong magnetic fields on grain growth in thin films with a magnetic extended phase field crystal (XPFC) model. The magneto-structural effects are incorporated into the correlation function in reciprocal space. With this approach magnetic anisotropy, magnetostriction and mobility of grain boundary can be controlled and a variety of geometrical and topological properties consistent with experimental results can be determined.
