In-plane resistance and magnetization measurements were performed oil La0.7Ca0.3MnO3/YBa2Cu3O7-delta/La0.7Ca0.3MnO3 (LCMO/YBCO/LCMO) trilayers below the superconducting transition temperature of the YBCO layer, Two magnetoresistance (MR) peaks were found: The first MR peak is consistent with the suppression of superconductivity due to the stray fields generated by the domain walls and the second one is most likely the result of the antiparallel orientation of the net magnetic moment of the top and bottom LCMO layers.
