In a superconducting spin valve (ferromagnet/superconductor/ferromagnet three-layer structure), the superconducting transition temperature (T_c) is controllable by the magnetization orientation of the two ferromagnets. However, the mechanisms of T_c modulation in a high-T_c superconducting spin valve have not been fully understood. In this study, we demonstrate the coexistence of two different types of T_c modulation in a high-T_c superconducting spin valve consisting of two ferromagnets with different conductivities.
