Phase separation of a homogeneous superconductor in a uhf radiation field
Dmitriev V.M., Khristenko E.V.
It was observed experimentally that at a certain critical uhf radiation power a superconductor undergoes a transition at a temperature below Tc from a homogeneous nonequilibrium state to an inhomogeneous nonequilibrium resistive state, which is characterized by the formation and development of a regular N-S structure with increasing power.
