Summary

The authors describe two magnetic techniques that may be used to determine the transport critical-current density of granular superconductors by measuring the intergranular magnetization of a sample. In the first method, magnetization critical-current density is used to estimate critical-current density by isolating the intergranular magnetization and applying the critical-state model. In the second method, magnetic detection is used to measure critical-current density directly; intergranular magnetization hysteresis loops are obtained while increasing a transport current through a sample. Both methods give values of critical-current density in fair agreement with values obtained from measurements.
