A fast photosignal has been obtained from epitaxial superconducting YBa2Cu3Ox thin films when a small alternating magnetic field was applied in the film plane. No bias current was required to observe this response. Pulsed infrared radiation at a wavelength of 10.6 μm and of 150-ns duration yielded nonlinear signals: the voltage pulses had approximately half the duration of the laser output. ...
