Abstract
Series arrays of two Josephson junctions were fabricated by focused electron beam (FEB) irradiation on YBCO films. The arrays show single junction like behavior with the coherent oscillations of the Shapiro steps in a array up to 2.8 mV. Microwave-induced Shapiro steps correspond to the double voltages Vn1= 2nVJ where VJ= foh/2e in two-junction arrays. The microwave power dependence of I-V curves shows the coherently oscillating steps corresponding to the resistively shunted junction (RSJ) model.
