Abstract

A systematic experimental study of transport critical current density of sintered high Tc ceramics was performed. A new contactless method was developed to measure the transport critical current in magnetic fields up to 6 T at temperatures ranging from 5 K to Tc. Reduction of critical currents due to trapped magnetic flux in the sample and the critical exponent characterizing the transition of the granular system to the coherent (zero voltage) state were determined from the measurements.
