Abstract:
This paper describes the results of experiments and theoretical simulations of the microwave-induced constant voltage substeps in the current-voltage (I-V) characteristics of a parallel array of Nb microbridge-type Josephson junctions. A parallel array consists of ten junctions and the spacing between adjacent junctions is 2 or 100 μm. For the array with 2-μm spacing, in which the propagation of fluxons is possible, substeps have been observed in I-V characteristics whose width is equal to half that of the fundamental constant voltage step associated with the propagation of fluxons in the array. On the other hand, for the array with 100-μm spacing in which the propagation of fluxons is impossible, no substep appears. The mechanism of the occurrence of substeps has been clarified by a numerical calculation of the equations of the equivalent circuit of the array including the effect of microwave radiation.
