Av. Arzumanov et al., SPECTRAL ASPECT OF THE ONSET OF SUBHARMONIC SHAPIRO STEPS IN A CHAIN OF JOSEPHSON-JUNCTIONS CONNECTED IN PARALLEL, Technical physics letters, 24(9), 1998, pp. 683-686
A chain of parallel-connected Josephson elements described by a resist
ive model is considered as a model for high-temperature Josephson junc
tions. The calculated spectra of the Josephson generation can account
for the experimentally observed subharmonic Sapiro steps on the curren
t-voltage characteristic and for their aperiodic dependence on the ext
ernal magnetic field. (C) 1998 American Institute of Physics.
