Magnetic and superconducting effects at the interface between cuprates and manganites

Thin-film-based multilayers from complex oxides can nowadays be grown with very high structural and chemical quality and atomically sharp interfaces. The proximity-effect in these artificial materials can give rise to entirely new physical properties and functionalities.

Nevertheless, the identification of the underlying mechanisms can be a rather challenging task since it requires experimental techniques that probe the relevant physical properties with a high depth resolution.

In my talk, I will focus on multilayers made from cuprate high-Tc superconductors and ferromagnetic manganites and I will show results from resonant x-ray absorption and reflectometry, polarized neutron reflectometry, and broad-band (THz-UV) spectroscopy. I will try to convince you that these cuprate-manganite multilayers have surprisingly versatile properties that may be very useful for “superspintronic” applications.
