"Investigation of interfacial electronic structure and magnetism in the oxide multilayers: Case study of YBa2Cu3O7/La1-xCaxMnO3 and LaNiO3/LaAlO3"

Presented by Heon-Jung Kim, Max Planck Institute for Solid State Research, Germany

Thursday, April 10, 2008, 1:30 pm — Small Seminar Room, Bldg. 510

Recent advances in thin film technology made it possible to manipulate charge, spin, and orbital states in transition metal oxides by changing epitaxial strain and/or by constructing artificial structures. The investigation of the electronic structure at interfaces and in geometrically confined systems, which cannot be achieved in bulk samples will not only give deeper insight of the present knowledge on the complex transition metal oxides but can potentially also generate novel electronic states at the interface. In this talk, I will present our on-going research on interfacial electronic structure and magnetism in YBa2Cu3O7/La1-xCaxMnO3 heterostructures, where superconductivity and magnetism coexist and on search for new electronic order in the LaNiO3 related multilayers. Special emphasis will be put on the synthesis of new functional oxide materials and the characterization of these materials by spectroscopic techniques.
