  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.
