Andreev reflection and spin polarization measurement of Co/YBCO junction
N. Ghosh, J. Barzola Quiquia, Q. Xu +4
We report temperature dependent Andreev reflection measurements of Co/ YBaCuO (YBCO) heterostructure samples with junction areas of 1 m diameter. Model…

Andreev reflections at large ferromagnet/high-T_C superconductor area junctions with rough interface
N. Ghosh, H. Schmidt, M. Grundmann
Sub-gap conductance at a large area junction with a rough interface of a ferromagnet and a high-T superconductor is superimposed by multiple peaks which is not expected from…
