Abstract

Josephson soliton oscillators integrated in a resonator consisting of two closely spaced superconducting microstrips have been investigated experimentally. The dc IV-characteristic shows zero-field steps containing a number of resonator-induced substeps, occurring because of locking of the soliton oscillator to the resonator. The position of the substeps follows the structure of a ''devil's staircase'', and their appearance depends strongly on the externally applied dc magnetic field.
