Magneto electric coupling in Multiferroic Oxides

Delft University of Technology, Time: 11:45 hrs, Location: Reactor Institute Delft Mekelweg 15, Curie-room

Multiferroic and magneto electric compounds allow coupling between the magnetic and electric moments. In recent years a number of compounds have been discovered that display such coupling, often introducing novel coupling mechanisms. In my talk I will discuss the magneto electric coupling in several transition metal oxides. We have probed the coupling by measuring the dielectric response in applied magnetic fields. The temperature and magnetic field dependence of the response identify the nature of the coupling mechanism, and can yield critical behavior near the phase transitions. Our measurements yield quantitative information about the nature of the coupling.
