The oxide heterostructures composed of superconducting YBa_2Cu_3O_7 bottom layer, the overlying ferromagnetic La_{1-x}Sr_xMnO_3 film and SrTiO_3 as ultrathin (d≈5 nm) barrier were grown heteroepitaxially onto LaAlO _3 substrates by applying pulsed liquid injection metalorganic chemical vapour deposition technique. We report anomalous interface resistance increase with cooling just below superconductive transition temperature (T_c≅85 K) and enhanced suppression of supercurrent of strip-like YBa_2Cu_3O_7 film due to spin-polarized carriers injected from the ferromagnetic manganite layer.
