N2 - Sm1+xBa2-xCu3Oy, (Sm-rich) had higher critical current density (J c) in magnetic fields and higher irreversible fields than stoichiometric SmBa2Cu3Oy (SmBCO) thin films. In this study, to clarify the features of artificial pinning centers (APCs) doped Sm-rich films, we prepared BaHfO3 (BHO)-doped Sm1+xBa2-xCu3Oy films with x = 0.00 ∼ 0.20 using combinatorial pulsed laser deposition (C-PLD) method on a metallic substrate and we evaluate surface morphrogies, crystal orientations and superconducting properties of the films. As a result, when x increased, the terrace width also increased. From the measurement of J c in magnetic fields, the BHO-doped Sm-rich films showed J c plateaus around 1 ∼ 3 T. From the angulaer dependence of J c, the BHO-doped Sm-rich films showed J c peak where B is parallel to c-axis. From several measurements, we discuss effects of Sm1+xBa2-xCu3Oy films with and without BHO on the superconducting properties.
