UPPER CRITICAL-FIELD AND RESISTIVE DATA OF HIGH-T-C FILMS IRRADIATED BY HE++ IONS

He++ ion irradiation effect on resistive characteristics and upper cri tical field H-c2(T) of YBa2CU3O7 and HoBa2Cu3O7 c-axis oriented films has been studied. Analyzing the normal states resistivity modification and T-c degradation with fluence F, we estimated the Hc(2)(T) change in GLAG theory. The -dH(c2)/dT rise with F has been found. The measure d resistive transition midpoint shift T-cH-T-c in magnetic field prove s higher, then one found from the estimated H-c2(T). So, the transitio n broadening has been found to be the main effect, determining the T-c H-T-c, at least for high fluences.
