Abstract:
Using the method of near-field microwave microscopy, we investigated the temperature dependence of the third harmonic power
P3ω(T) of superconductor – normal metal MoN/Al structures with proximity effect. The presence of an additional (low-temperature) maximum and vanishing in the dependence P3ω(T) for the MoN/Al structure, which disappear when a weak perpendicular magnetic field is applied.
Keywords:
nonlinearity, microwave, superconductor – normal metal structure, near-field microwave microscopy.
