摘要：

YBa2Fe3O8(YBFO) epitaxial films are prepared on (100) SiTrO3 single crystal substrate by polymer-assisted non-fluorine chemical solution deposition (CSD) method. The influence of firing temperature on texture degree, microstructure, and physical properties of YBFO films is systematically investigated by x-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and SQUID magnetometer. YBFO film fired at 1070 A degrees C exhibits best epitaxial quality with FWHM value of (103) phi-scan and (005) omega-scan is 0.19A degrees and 0.45A degrees, respectively, and highly dense and smooth morphology. A weak ferromagnetism transition was observed at 68 K in the YBFO film.
