Scientific Profile:

Dr. rer. nat. Semih Ener is an experienced postdoctoral researcher in the Functional Materials group of Prof. Gutfleisch since 2013. Before joining to Functional Materials group he completed his doctoral study at the Physics Department of Technische Universität München on the topic of lattice dynamics in ferromagnetic shape memory alloy system Ni-Mn-Ga. He is an expert in sample preparation (single- and poly-crystalline), structural (neutron and x-ray diffraction), microstructural (scanning electron microscopy) and magnetic characterization (PPMS, VSM, Kerr microscopy) and has a great experience in elastic/inelastic neutron scattering. Before coming to Germany, he finished his M.Sc. and B.Sc. studies in Physics Department of Ankara University, Turkey which gave him the expertise on solid state physics and magnetism. Currently, he is working on the topics of rare-earth free and rare earth lean permanent magnet materials and magnetocaloric materials.
