摘要：

Effects of 2.5 MeV Ni2+ ion irradiation on thin films of high-T(c) oxide superconductor Ba2YCu3O7-x were investigated in the fluence range 1.0 x 10(9) cm-2 < phi-t < 3.0 x 10(14) cm-2. An increase of transport J(c) due to irradiation was observed below 1.0 x 10(10) cm-2 in phi-t, while above this fluence, both T(c) and J(c) decreased. In X-ray diffraction (XRD) measurement, decrease in intensity and increase in the full width at half maximum (FWHM) value of peaks and in the c-axis lattice constant were observed above 1.0 x 10(13) cm-2 in phi-t.
