Abstract
Conductance spectra of Co/Au/I/Bi2Sr2CaCu2Ox+8(BSCCO) tunnel junctions have been measured to investigate the tunneling of spin polarized quasiparticles. BSCCO thin films prepared by molecular beam epitaxy are used for the Co/Au/I/BSCCO tunnel junctions because those have flat surface without any large steps as observed on the cleaved surface of single crystals. The superconducting gap is clearly observed in the conductance spectra at the temperature below the critical temperature Tc. In addition, a splitting of the zero bias conductance peak and the imbalance of the peak heights are observed. This feature is induced by the spin polarization of quasiparticles injected into the superconductors.
