Current-carrying capability of GdBa2Cu3O7−x HTSC tapes in magnetic fields in the temperatute range of 2–100 K

The current-carrying capability of the second-generation HTSC tapes based on GdBa2Cu3O7−x (GdBCO), produced by the SuperOx Company by the pulsed laser deposition method is studied. Critical currents inmagnetic fields aremeasured by resistive andmagnetic (using a SQUID magnetometer) methods. The results obtained are compared with characteristics of an YBCO tape grown by chemical deposition (SuperPower, USA).
