Abstract

It is known that BaZrO3 and Ag can improve the magnetic and transport performance of YBCO thin film through totally disparate ways. BaZrO3 plays the role of flux pinning centers and Ag improves the transparency of the YBCO grain boundaries. However, similar research is rare on the fluorine-free derived YBCO films. In this research, BaZrO3-doped, Ag-doped and BaZrO3/Ag hybrid-doped YBCO films were synthesized through a fluorine-free metal–organic deposition method. BaZrO3 was found to deteriorate the microstructure and performance of YBCO, while Ag-doping was found to enhance the crystallization of YBCO and resulted in a high Jc of 3.87 MA/cm2 in self-field at 77 K. However, the microstructure and performance of the BaZrO3/Ag hybrid-doped YBCO film showed that the positive impact of Ag-doping was totally overwhelmed by that of BaZrO3.
