Abstract
High pulsed currents with a duration varying from 1.25 to 20 ms have b een applied at 77 K to sintered and textured samples. For I > I-c, two types of behaviour are observed: when the average temperature of the sample is lower than T-c, a critical current is recovered at the end o f the pulse, Above T-c, samples remain normal after the pulse because the sample temperature is too high leading to a maximum instantaneous applied power up to 182 GW/m(3) in the sintered sample. At 15I(c) elec tric fields of 400 V/m and 1000 V/m are observed for the sintered and textured samples respectively.
