I/sub c/R/sub n/ products up to 100 mu V were achieved, and well-pronounced Shapiro steps under 8-GHz microwave radiation were observed at 77 K. Macroscopic quantum interference was clearly registered in double microbridge structures at the same temperature.<<ETX>>

  • Self-field effects in intrinsic Josephson junction stacks in (Bi,Pb)/sub 2/Sr/sub 2/CaCu/sub 2/O/sub y/ single crystals

    We have studied the features of intrinsic Josephson junction stacks in the c-axis direction in highly Pb-substituted (Bi/sub 1-x/Pb/sub x/)/sub 2/Sr/sub 2/CaCu/sub 2/O/sub y/ (with x/spl ges//spl sim/0.2) single crystals exhibiting multiple branches with hysteresis on the I-J characteristics. For the mesa of the single crystal with x=/spl sim/0.2, as the self-field effects on the fluxon motion in the Intrinsic Josephson junctions, the flux flow branch and the zero field step were successfully observed in addition to the supercurrent at zero voltage and the multiple resistive branches. Moreover, their ac Josephson effect was also confirmed by observation of the microwave-induced Shapiro step. These results imply the existence of intrinsic Josephson effects in the single crystals with x/spl ges//spl sim/0.2.

    The authors fabricated Y-Ba-Cu-O/Au/AlO/sub x//Nb and Y-Ba-Cu-O/AlO/sub x//Nb Josephson tunnel junctions using electron-beam evaporation of Al and Nb films and natural oxidation. Sintered Y-Ba-Cu-O was used as the base electrode. Superconducting Josephson current and hysteresis of the current-voltage characteristics, which are typical features of Josephson tunnel junctions, have been observed at 4.2 K. RF-induced voltage steps at a voltage greater than 0.4 mV have been clearly observed, and RF-induced subharmonic steps have also appeared. The superconducting Josephson current was modulated by the magnetic field.<<ETX>>

  • RF driven long Josephson junctions

    An analysis of the behavior of zero-field resonances in long Josephson tunnel junctions under the influence of RF fields is performed. The measurements lead to establish some criteria under which fluxon oscillations are stable. The stability is investigated mainly via the relation between the amplitude of the current singularities and an external magnetic field. We find that the junction is able to support the fluxon's steady motion almost as long as the amplitude of the RF signal does not disrupt the d.c. Josephson current.
