Abstract
We report detailed transport studies on ferromagnet-superconductor heterostructures. Epitaxial heterostructures of half-metal colossal magnetoresistive La2/3Ca1/3MnO3 (HM-CMR) and high Tc superconducting YBa2Cu3O7 (YBCO) are grown on SrTiO3 (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 Rab (T) in the case of injection along the c-axis that is discussed to be related to the opening of a pseudogap.
