Abstract

We study the generation of supercurrent by circularly polarized electromagnetic wave in a superconducting ring in fluctuation regime at T>Tc. Using the time-dependent Ginzburg-Landau equation with a complex relaxation constant we calculate the dc component of the supercurrent, which is the manifestation of the inverse Faraday effect. The observed strong dependence of the current on the radiation frequency and temperature can be additionally enhanced by the application of an external magnetic flux and may represent a distinct feature noticeable in experiments.
