Abstract

The transport critical current of bulk sintered YBa2Cu3Ox has been measured at 77 K in the presence of static and sinusoidally-time-dependent (10–100 Hz) magnetic fields. In all cases, the field required for a given reduction of critical current density was independent of frequency to within ~10%.
