Magneto-electro-optical Interaction and their dynamics of oxide heterostructures (B03)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2008 to 2019
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 31047526

Aim is to develop a remanently switchable optical waveguide, in which the switchable magnetisation or elec-tric polarization fields of a ferroelectric, ferromagnetic, or multiferroic material is used to switch the proper-ties of resonant or propagating optical modes as a signal. To this end we will investigate (1) basic optical and magneto-optical properties of, primarily, magnetic spinels and multiferroic BaTiO3/BiFeO3-composites; (2) the influence of the mentioned fields on the optical properties of an adjacent dielectric or semiconduc-tor; (3) the dynamics of their switching in the fs- to ms-time-range.
