Michael Fechner

Dr. Michael Fechner is a researcher at the Institute of Physics, affiliated with the Faculty of Natural Sciences II - Chemistry, Physics and Mathematics at Martin Luther University Halle-Wittenberg. His work focuses on theoretical investigations in quantum solid-state physics, particularly at multiferroic interfaces and field-emission states.

• Education:
  • Diploma Thesis (2010): Dispersion relation of field emission states, analyzing quasi-discrete states induced by tunneling tips via two-dimensional modeling of z(V) spectroscopy and differential conductance.
  • Doctoral Thesis: Magnetoelectric coupling at multiferroic interfaces, exploring ab-initio methods to study polarization-dependent magnetic switching in ultrathin Co/Fe layers on ATiO3 perovskites.
• Research Interests:
  • Investigating magnetoelectric effects in multiferroic systems, where magnetic and ferroelectric order coexist, enabling cross-control via electric/magnetic fields.
  • Theoretical modeling of quantum phenomena in condensed matter, including electronic structure calculations (DFT), hybridization effects at interfaces, and nanoscale magnetic instabilities.
  • Exploring tunneling processes in one-dimensional potential barriers, with applications to scanning tunneling microscopy/spectroscopy.

His findings on magnetization thickness dependence in Fe layers and polarization-induced switching mechanisms contribute to advancements in nanoscale spintronics and multiferroic device design. He has developed computational models to simulate experimental observables, aiding in interpreting field-emission dispersion relations and tunneling dynamics.
