Abstract :
Microwave-induced steps were observed in I-V characteristics of intrinsic Josephson junctions fabricated on an overdoped BSCCO single crystal with a weak magnetic field parallel to the c-axis. Voltage intervals between the steps under the irradiation of 12.2, 13.2 and 13.9 GHz microwaves were independent of the microwave power and proportional to the frequency. From the measurement of voltage intervals, it was found that all the junctions in the fabricated junction stack simultaneously produced Shapiro steps, assuming that the steps are Shapiro steps.
