中文摘要	Solution techniques are low cost non-vacuum methods for coated conductor development, which are promising in obtaining high quality YBa /sub 2/Cu/sub 3/O/sub 7-x/ (YBCO) films. However, many pores and cracks are often formed in the YBCO film prepared by solution techniques, which degrades the film qualities. In this paper, we report a new method for modification of the structural and superconducting properties of YBCO film, namely, ion beam structure modification (ISM). Experimental results show that ISM is an effective way to eliminate the pores existed in solution deposited YBCO film. Denser and smoother films with improved c-axis grain alignment and grain connectivity have been obtained using ISM. The superconducting properties of the YBCO film are also improved.
