Abstract
The effects of dc transport current on low-field microwave absorption have been investigated systematically on bulk ceramic YBa₂Cu₃O₇-δ samples. At a fixed temperature T, the critical current Ic (T) at which the electron paramagnetic resonance (EPR) signal vanishes varies linearly with T. The EPR absorption characteristics obey a scaling rule in accordance with the flux creep model. A revised version of the flux creep model is also presented.
