The XRD patterns of (a) LAO substrate, (b) NSMO single layer, (c) YBCO single layer, and (d) NSMO/YBCO bilayer.
(a) Magnetization vs temperature curve for NSMO/YBCO bilayer. The closed circles and the open circles represent zero-field-cooled (ZFC) and field-cooled (FC) data, respectively. The curves for YBCO and NSMO are shown in the upper and the lower insets, respectively, for ZFC data. (b) Temperature dependence of critical current density at (open circles) and 0.5 T (close circles).
