Summary

Low-temperature (4.2 K) magnetic and electrical transport studies in high-magnetic fields (5 T) reveal that the addition of silver into GBCO enhances the magnetic critical current density, volume pinning force, flux expulsion, and transport critical current density. Microwave-induced direct-current voltage studies show the reduction in the total number of weak links between superconducting GBCO grains with increase in silver concentration. The flux creep rate was also increased with increase in silver concentration in GBCO resulting in stronger pinning potential.
