Magnetic induced/enhanced coarsening in thin

External magnetic fields allow to influence the microstructure in polycrystalline materials. Using a phase-field-crystal model we explore the influence on long time scaling and various geometrical and topological properties of grain structures in thin films. For parameters which lead to stagnant coarsening without magnetic fields, we observe two different linear scaling regimes if a magnetic field is considered. In the first the scaling exponent depends on the strength of magnetic interaction. After sufficient coarsening the texture becomes dominated by grains with their easy axis aligned to the magnetic field. This leads to an increase of low angle grain boundaries, reduces the influence of the magnetic field and leads to a second linear scaling regime with the exponent independent on the magnetic field. We further study the influence of the magnetic field on the grain size distribution (GSD), next neighbor distribution (NND) as well as grain shape and orientation and compare, if possible, with experimental results.
