Effect of Ion Irradiation of the Second-Generation HTSC GdBa2Cu3O7 –x Ribbons on the Critical Parameters of Superconductor
2019
This work studies the effect of irradiation defects induced by 132Xe27+ (167 MeV), 86Kr17+(107 MeV), and 40Ar8+(48 MeV) ions on the critical properties of the second-generation superconducting GdBa2Cu3O7 –x-based ribbons (free from copper coating) produced by the SuperOx domestic company. Dependences of the critical current at 77 K in the self magnetic field and the critical temperature and width of the superconducting transition on the ion-irradiation fluence have been obtained. The ion-irradiation resistance of superconductor has been determined. The critical ion fluence value, at which the critical temperature is zero, was used to estimate the track radii in the superconductor.
