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 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.

Josephson pi state in a ferromagnetic insulator.
TLDR
It is shown that a stable pi state can be realized in junctions based on high-T{c} superconductors with a La2BaCuO5 barrier and the mechanism of the 0-pi transition can be attributed to thickness-dependent phase shifts between the wave numbers of electrons and holes in FI.
Theory of Josephson transport through spintronics nano-structures
