We present a utilization of the inverse proximity effect in superconductor-ferromagnet (S-F) bilayer to generate lateral Josephson junctions. The weak link is created by a Pd(0.95)Fe(0.05) strip across a Nb bridge. Close to T(C) and in perpendicular magnetic field the junctions exhibit a modulation of the critical current I(C)(B) similar to a Fraunhofer interference pattern which proves the dc ...

We present a utilization of the inverse proximity effect in superconductor-ferromagnet (S-F) bilayer to generate lateral Josephson junctions. The weak link is created by a Pd(0.95)Fe(0.05) strip across a Nb bridge. Close to T(C) and in perpendicular magnetic field the junctions exhibit a modulation of the critical current I(C)(B) similar to a Fraunhofer interference pattern which proves the dc Josephson effect. The structure contains three weak links (two different areas) in series which result in the observation of two periods scalable with the areas penetrated by magnetic flux. Measurements of Shapiro steps prove the presence of the ac Josephson effect.
