Abstract: Transport across a CrC2/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 spin-polarization of CrO2 film, even after exposing to air, remained close to 100% to the T c of YBa2Cu3O7− x , a temperature limited by this method.
