Josephson critical current was measured through a pseudospin-valve (PSV) structure. The PSV consisted of two F layers with different coercive fields, separated by a Cu spacer. The magnetoresistance of the PSV provided direct access to information about the relative orientation of the Co and Py layers, and the magnetic state of the barrier. The results show that Josephson critical current can be controlled by putting PSV into parallel and antiparallel remanent states.
