Abstract
New approach to measure a magnetic component of a microwave radiation via sub-harmonic mixing in high-Tc superconductor Bi2Sr2CaCu2O8 layer kept close to the transition temperature Tc is suggested. Employing an electrical nonlinearity near the transition, we have mixed alternating electrical field of 1 MHz and 2 MHz frequencies in the sample placed on the narrow wall of the waveguide for 10 GHz frequency range. The recording principle is illustrated showing the relation between the amplitude of the mixing signal and the microwave magnetic field component in a standing wave experiment. The underlining idea is also confirmed by experimental data obtained measuring the third order nonlinearity recorded by the application of the double-modulation approach in the microwave range.
