Head of research group: PD Dr. Sebastian Fähler

Ferroic materials comprise ferromagnetic, ferroelastic and ferroelectric materials. These functional materials react to external stimuli like temperature, magnetic or electric fields, and stress, which enables new functionalities. We cover the complete range of current scientific question, from fundamental aspects on the underlying principle, preparation of better materials to the implementation in novel devices. We analyze (magnetic) shape memory alloys films, which are suitable for microsystems and use epitaxial films as a model system to understand the formation of the martensitic microstructure and to examine the influence of fast martensitic transformation. On the application side, we focus on the conversion of low-grade waste heat to electricity. For this, we use two different material classes: ferromagnetic materials and ferroelastic shape memory alloys.
