Thermally induced 0-pi phase transition in Josephson junctions through a ferromagnetic oxide film

Abstract

We investigate the Josephson transport through a ferromagnetic oxide film, e.g., La${}_2$BaCuO${}_5$, theoretically. Using the recursive Green's function technique, we found the formation of a pi-junction in such systems. Moreover the 0-pi phase transition is induced by increasing the temperature. Such ferromagnetic-oxide based Josephson junctions may become an element in the architecture of future quantum computers.
