Abstract

Infrared pulsed laser irradiation has been used to generate a fast photosignal from epitaxial YBa2Cu3Ox superconducting films when a small alternating magnetic field is applied in the film plane. No bias current was applied, and no signals were observable in static magnetic fields. The photosignals, 40 ns in duration and tenths of a millivolt in amplitude, are obtained below Tc, with alternating ...
