Abstract(in English) We have been studying a RF-Field-modulated(driven)DC SQUID(RFDS)that exhibits RF-induced-current-steps larger than those of single junctions at lower normalized frequency. In RFDS, adjusting DC magnetic field can control the order of generated steps. Even order steps are dominant in the absence of DC magnetic field, which DC magnetic field of a half flux quantum enhances odd order steps dominantly. Due to the remarkable constant voltage steps, RFDS is expected for switching device applications based on high-Tc Josephson junctions. We numerically investigate the switching properties of RFDS for various bias conditions, including RF circulating currents and DC bias current to obtain the optimum switching operation.
