Abstract

YBCO films were grown on CeO₂/YSZ/CeO₂ buffered rolling-assisted biaxially textured substrates (RABiTS) by pulsed lased deposition (PLD). CeO₂ cap layer was deposited prior to YBCO growth. CeO₂ cap layers of different thickness were prepared to evaluate the thickness dependence of the YBCO films. The microstructure and surface morphology of the films were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). It is found that the thickness of the cap layer can remarkably affect the preparation of the subsequent YBCO layer. The possible mechanisms responsible for the dependence of the structure and the preparation of the YBCO films on the thickness of the CeO₂ cap layers are discussed.
