Abstract: Transport across a CrC<subscript>2</subscript>/Ag/YBCO interface was studied using a flip-chip configuration. The results were interpreted in the Andreev reflection scenario. It is shown that the surface spinpolarization of CrO<subscript>2</subscript> film, even after exposing to air, remained close to 100% to the T <subscript>c</subscript> of YBa<subscript>2</subscript>Cu<subscript>3</subscript>O<subscript>7− x </subscript>, a temperature limited by this method.
