摘要

We report detailed transport studies on ferromagnet-superconductor heterostructures. Epitaxial heterostructures of half-metal colossal magnetoresistive La_(2/3)Ca_(1/3)MnO_3 (HM-CMR) and high T_c superconducting YBa_2Cu_3O_7 (YBCO) are grown on SrTiO_3 (100) single crystal substrates by pulsed laser deposition. Using the HM-CMR layer as source for spin-polarized quasiparticles, we show the effect of injection of spin-polarized quasiparticles into the ab-plane and along the c-axis of YBCO. The results show a drop in the ab-plane resistance R_(ab) (T) in the case of injection along the c-axis that is discussed to be related to the opening of a pseudogap.
