Abstract

We studied the orientation and superconducting properties in (Yb 1-xNdx)Ba2Cu3Oy (Yb/Nd123) thin films as a function of Yb/Nd composition ratio x. As a results, we needed so high oxygen pressure as to increase x for obtaining the c-axis oriented films. Jc-B curves in the Yb/Nd123 thin films were superior to that in YBa2Cu3Oy thin film. Since a RE fluctuation in a composition in the Yb/Nd123 thin films was observed with TEM-EDX, we speculated the pinning centers in the Yb/Nd123 thin films were strongly affected by the RE fluctuation.
