摘要：

Epitaxial barriers of ferromagnetic SrRuO3 have been used to fabricate high T(c) superconductor-normal-superconductor Josephson junctions in the edge junction geometry. At small barrier thicknesses the SrRuO3 junctions follow the behavior of nonferromagnetic but otherwise closely related CaRuO3 junctions. A rapid disappearance of critical current is observed when the barrier thickness is increased to 250 angstrom. Possible origins of such a large critical thickness are discussed.
