The resistivity of YBa2Cu3Oy/SrRuO3 (YBCO/SRO) multilayers was measured to investigate the effects of the magnetic ordering on superconducting properties. The YBCO film is superconducting at 90 K while SRO films show a ferromagnetic ordering at about 160 K. The T, of YBCO/SRO multilayers is reduced due to the presence of the SrRuO3 layers. The anisotropic superconducting parameters of YBCO/SRO multilayers are derived.
