Abstract

We investigate the Josephson transport through a ferromagnetic oxide film, e.g., La2BaCuO5, theoretically. Using the recursive Green's function technique, we found the formation of a π-junction in such systems. Moreover the 0-π 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.
