Measurements of the magnetic field dependence of Fiske steps and ’’zero‐field’’ steps in Nb–Nb oxide–Pb Josephson junctions are described. By the use of a simple variable dc bias scheme, the measured ac volt‐ampere characteristics are made to clearly exhibit the step structure even in the presence of a large dc Josephson current. A comparison with the theory of Kulik for the magnetic field dependence of Fiske steps is shown and the correlation is very good for small L/λj ratios. Deviations for…

Self‐resonant current steps of Josephson tunnel junctions in the presence of multimode oscillation
Taking into account the presence of multimode oscillation, self‐resonant current steps in current‐voltage characteristics of rectangular Josephson tunnel junctions are studied theoretically. An

Resonances in the current‐voltage characteristics of interferometers with two Nb‐NbOx‐Pb window junctions have been experimentally investigated. The data are compared with the theoretical curves
Field dependence of Fiske resonances in Nb-AlO/sub x/ based Josephson junctions
Fiske resonances have been measured in a rectangular Nb-Al, AlO/sub x/, Al-Nb Josephson junction as a function of the magnetic field applied parallel to a junction side. Due to the high quality

The effect of an external magnetic field on zero-field resonances is investigated analytically. A calculation shows that the even-mode current height falls smoothly to zero as the external field

dc and ac Josephson Effect in Sputtered Nb–NbOx–Pb Junctions
The magnetic field dependence of the maximum dc Josephson current and of the ac Josephson‐effect‐induced step structure have been measured for sputtered Nb–NbOx–Pb Josephson junctions, and found to

Measurements of the maximum Josephson current with temperature for Nb−NbOx−Pb junctions differ from the BCS Ambegaokar−Baratoff curve. This cannot be explained in terms of strong coupling effects. A
