| Research Abstract |
The hybrid structures of ferromagnet and intrinsic Josephson junctions in Bi 2212 high-Tc superconductor were fabricated and spin dependent transport properties in them were studied. It was found by a micro-magnetics analysis that the observed magnetic field dependence of critical currents was strongly associated with a domain structure of ferromagnetic electrode formed on the intrinsic Josephson junctions. The obtained results indicates a potential for the novel spintoronics device application of such hybrid structures.
