摘要：
Single nonhysteretic superconductor-metal-superconductor Josephson junctions consisting of Nb-Ti-Nb were prepared using the well-known anodization process for the isolation of the junctions. The 4 x 4 mu m(2) junctions show overdamped Josephson current-voltage characteristics at 4.2 K. The characteristic voltage IcRn is about 8.0 mu V at a critical current density j(c) of about 29 kA/cm(2). Under the influence of 10.5 GHz microwave irradiation the constant-voltage steps of n=0 and +/-1 are observed with current amplitudes of about 3 mA. (C) 1998 American Institute of Physics.
