Manipulating microstructures by means of magnetic fields — •Thomas Brede1, Fernando Maccari2, and Rainer Backofen3 — 1Institut für Materialphysik, Universität Göttingen, Deutschland — 2Institut für Materialwissenschaften, Technische Universität Darmstadt, Darmstadt — 3Institut für wissenschaftliches Rechnen, Technische Universität Dresden, Dresden
In this project, the isolated influence of strong magnetic fields on the development of the microstructure of ferromagnetic thin films during annealing processes is investigated. For this purpose, thin films out of Iron, Nickel and Cobalt are prepared and characterized, then heat treated in the same heater with and without magnetic field and subsequently characterized. The experiments are accompanied by phase field crystal modeling to separate the different possible influences on the microstructure.
Through the parallel approach of experimental and modeling work, the effect of external magnetic fields on the development of microstructure and grain orientation will be investigated to understand the direct effect of the magnetic field. Through a deeper understanding of the isolated influence of a magnetic field, additional conclusions should be possible about the influence of induced magnetic fields in the case of sample treatment with high currents.
