Critical exponent of the electrical conductivity in the paracoherence region (
γ ) of the high temperature superconductor YBa2Cu3O7−x (YBCO) has been estimated for high quality thin film on ZrO2 substrate prepared by high pressure oxygen sputtering. High energy ion irradiation was carried out using 100 MeV16O7+ ions at liquid nitrogen temperature to see the effects of disorder on the value of the exponent. The critical exponent (γ ) changes from a value of about 2 to 1·62 upon irradiation. Studies were also carried out on this film to see the effect of ageing and annealing.
