Abstract

We calculated the current distribution in a coated conductor (CC) from magnetic induction profiles measured using the scanning Hall probe method. An external magnetic field was applied in the normal direction with respect to the tape surface and was decreased stepwise from H_peak to -H _peak. From the hysteretic behavior of the current distributions, the energy loss, Q_M, was calculated for various values of H _peak. Comparison of the present results with Brandt's theoretical calculations revealed that his formula is still valid if one substitutes the magnetic field dependent critical current density into his equation. The theoretical results obtained were consistent with the experimental Q_M values obtained.
