The “critical” current/width vs magnetizing field for thick superconductor at , measured with -axis under various measurement conditions of transport, swept field vibrating sample magnetometry, and SQUID-based magnetometry. Values of (the slope in the log-log graph that characterizes the falloff of with ) vary systematically with electric field level.
Values of vs level of -field, as observed at the temperatures indicated.
Current-voltage characteristics at , presented as electric field vs current/width as measured in applied magnetic fields . Data from various experimental methods are indicated by open, filled, and half-filled symbols. Numerical values show the current-voltage power law index obtained from slopes in the log-log plots.
Current-voltage characteristics extending to low temperatures for a magnetic field applied along the -axis. Corresponding -values are indicated.
