Abstract By measuring the imaginary part of the magnetic susceptibility of a GdBa2Cu3O7-x film, we found the effect of N2, O2 and Ar molecules low temperature adsorption on the superconducting properties of the film. The low temperature adsorption of the gases affects the critical transport current and the transition temperature. In all cases, the transition region broadens, as the degree of coverage of the film with the gas molecules increases. By processing the experimental data, we found the critical current either growing linearly (for argon and nitrogen) or decreasing exponentially (for oxygen) with increasing surface coverage by the adsorbed gas molecules.
