Abstract We have grown PrBa2Cu3O7−x (PBCO) thin films on (100) SrTiO3 substrates using pulsed laser deposition (PLD). X-ray diffraction (XRD) studies indicate that the orientation of PBCO films varied with increasing deposition temperature: b axis oriented films can be grown at 680°C, and a axis oriented films at the temperature between 692°C and 705°C. Atomic force microscopy (AFM) reveals that a good flatness of the films was obtained with surface mean roughness of less than 24 Å, indicating that it is suitable for use as template layers in a axis oriented epitaxial YBa2Cu3O7−y /PBCO and YBCO/tetragonal–YBCO/PBCO multilayer structures.
