Notes:
We report on the observation in current–voltage characteristics of YBa2Cu3O7−δ (YBCO) step-edge Josephson junctions of resistive branches generated by a current injected close to the grain-boundary region through two symmetrical Au/YBCO contacts. The current amplitude and voltage tunability of the branches is measured as a function of injected current and sample temperature and the observed effects are explained in terms of flux-flow dynamics in long Josephson junctions. As the voltage of the branches can be tuned up to 2.5 mV, the investigated phenomenon is also appealing for practical applications in the submillimeter-wave range of the electromagnetic spectrum. We estimate the available power and the linewidth of the electromagnetic radiation associated with typical bias points. © 2000 American Institute of Physics.
