R. G. Herb Condensed Matter Seminar
Interplay between superconductivity and ferromagnetism at the LaAlO3/SrTiO3 interface
Time: 3:30 pm
Place: 5310 Chamberlin
Speaker: Venkat Chandrasekhar, Northwestern University
Abstract: The interface between the two band insulators LaAlO3 (LAO) and SrTiO3 (STO) has proved to be host to a rich variety of phenomena, including electric field controlled metal-insulator and superconductor-insulator transitions and ferromagnetism. Recently, ferromagnetism and superconductivity, two normally antagonistic phenomena, have been shown to coexist at the interface. We shall discuss the influence of the ferromagnetism on the superconducting properties of the system. In particular, we show how the magnetization dynamics in the ferromagnet can be used as a tool to explore the superconductor to insulator phase transition.
