N2 - The coexistence of superconducting and magnetic ordering has attracted much attention for fundamental physics as well as applications, particularly in the hybrid systems of superconductor (SC)/ ferromagnet (FM). The magnetic exchange field of ferromagnetic coupling tends to break the symmetry ordering of superconductor;1 whereas the cooper pairs penetrate into magnetic matter and also cause the proximity effect at the interface.2 Among many, the enhancement of critical current density of high-Tc superconductors via magnetic pining is one of the important subjects in electronics. RBa2Cu3O7-d (R = Y or rare earth element)-type superconductors are favorite candidates for applications because of their well-controlled pinning properties in magnetic field. The strengthening of pinning potential can be achieved via the addition of impurity phases by chemical mixing,3 columnar defects generated by heavy ion irradiation,4 and point defects generated by oxygen deficiency or chemical substitution.5 In this study, we report the effects of magnetic proximity on flux pining in high-Tc superconductor YBa2Cu3O7-d (YBCO) by capping a C-type antiferromagnetic insulator Nd0.35Sr0.65MnO3 (NSMO) on top of it.
