Abstract:	Hysteresis behavior of transport critical current density for an Ag-sheathed BiPbSrCaCuO superconducting tape is measured. The experimental data are obtained by zero field cooling (ZFC) process at 77 K under field cycle, and the values of critical current density Jc measurements are determined by various criteria down to very low voltage (<10−9 V). An effect remnant magnetic field Hm associated with flux pinning force can be obtained by the transport hysteresis Δ Jc(H) which is defined as the difference between the transport critical current Jc(H) in an increasing field and decreasing field. The magnetic hysteresis using SQUID is also measured and compared with transport hysteresis behavior.
