FOR 404:  Oxidic Interfaces

• Subject Area: Physics
• Term: from 2000 to 2005
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 5467439

Main subject of the investigations are interfaces and surfaces of transition metal oxides mainly in form of thin films, which are characterized by partial occupation of d levels and therefore may develop interesting magnetic and ferroelectric properties. The research concerns the electronic and geometric structure, electric transport properties, the formation of ferroelectric and magnetic domain structures and order. The projects are devided into two areas "structure and magnetism" and "transport and dynamics". The research concentrates on preparation and characterization of thin oxide films and their interfaces, on the measurement of magnetic and ferroelectric order and their dynamics, on magnetotransport, on theelectronic structure and on the investigation of the non-linear optical properties of such systems.
