Abstract
Superconductivity can be quenched at large dc currents and it can be stimulated by a high-power microwave ac stimulus. Here, the authors investigate the dc- and microwave-driven quenching in a Nb superconductor in the presence of vortices and the factors contributing to the competition between the stimulation and quenching of the superconducting state.
