P. Caputo et al., MAGNETIC-FIELD BEHAVIOR OF RESONANT CURRENT STEPS IN ONE-DIMENSIONAL ARRAYS OF JOSEPHSON TUNNEL-JUNCTIONS, Czechoslovak journal of Physics, 46, 1996, pp. 699-700
We study the magnetic field behavior of the resonant current steps app
earing in one dimensional arrays of Josephson tunnel junctions. The an
alysis is carried out in the framework of the Kulik theory of resonanc
es in small Josephson junctions, and the theoretical maximum current a
mplitude of tile Fiske steps is computed as a function of the applied
magnetic field. Preliminary measurements of the Fiske step current mod
ulations induced by varying the magnetic field is also reported and di
scussed.
