P. Barbara et al., EXPERIMENTAL-STUDY OF THE INTERACTION BETWEEN FLUXON ARRAYS IN STACKED JOSEPHSON-JUNCTIONS, Physics letters. A, 191(5-6), 1994, pp. 443-448
Stacks of two Nb/Al/AlO(x)/Nb long Josephson junctions have been inves
tigated experimentally. The fabrication process of the samples provide
s a connection to their common electrode. We report the first experime
ntal data which show the interaction between fluxon arrays in the two
junctions.
