Abstract

To increase critical current density (J C ) in magnetic fields (B) parallel to the c-axis, 2-dimensional artificial pinning centers (APCs) are introduced into YBa 2 Cu 3 O 7-δ (Y123) films. Multilayer films alternately stacked a-axis oriented Y123 and Pr123 (Y123/Pr123 multilayer films) have been grown on SrLaGaO 4 substrates by pulsed laser deposition. Magnetic field angular dependences of the J C showed peaks not only in B // a-axis but also in B // c-axis of the Y123/Pr123 multilayer films. This result indicates that the Y123/Pr123 multilayer films have c-axis-correlated pinning centers. Consequently, it is suggested that the Pr123 layers act as 2-dimentional APCs.
