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/ Y${}_1$Ba${}_2$Cu${}_3$O${}_{7-\delta }$ (YBCO) heterostructure samples with junction areas of 1 $\mu$m diameter. Model…
