Abstract
Voltage‐current characteristics of a superconducting closed loop which consists of a parallel combination of two linear series arrays of N‐Josephson junctions are theoretically and experimentally investigated for N=3. The results show that the rf‐induced constant voltage steps in v‐i characteristics in the presence of the rf radiation of frequency F appear at voltages corresponding to nNFΦ0 with an integer n. We find that the junctions show a coherent behavior even though the closed loop does not consist of identical junctions. The voltage standard application of this circuit seems feasible.Keywords
