Abstract

A multilayer alternately stacked a-axis oriented YBa ₂ Cu ₃ O _7-δ and PrBa ₂ Cu ₃ O _7-δ (Y123/Pr123 multilayer) has been grown on a SrLaGaO ₄ substrate with a Gd ₂ CuO ₄ buffer layer by pulsed laser deposition. We used an Y123 target that contains a Pr123 sector for obtaining the Y123/Pr123 multilayer. The multilayer structure of the obtained film was confirmed by a transmission electron microscope. In magnetic field (B) angular dependences of critical current density (J _C ) (J _C -B-θ curves), J _C peaks were observed at B∥a-axis and B∥c-axis of the Y123/Pr123 multilayer. Peaks at B∥c-axis are absent in J _C -B-θ curves of pure a-axis oriented Y123 films. Therefore, peaks at B∥c-axis in J _C -B-θ curves of the Y123/Pr123 multilayer are attributed to Pr123 layers. This result indicates that the Y123/Pr123 multilayer has c-axis-correlated pinning centers. Consequently, it is concluded that Pr123 layers work as two-dimensional artificial pinning centers with the current direction along the b-axis.
