Abstract: We investigate the Josephson transport through a ferromagnetic oxide film,e.g., La$ 2$BaCuO$ 5$, theoretically. Using the recursive Green-s functiontechnique, we found the formation of a pi-junction in such systems. Moreoverthe 0-pi phase transition is induced by increasing the temperature. Suchferromagnetic-oxide based Josephson junctions may become an element in thearchitecture of future quantum computers.
