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 contai ning a number of resonator-induced substeps, occurring because of lock ing of the soliton oscillator to the resonator. The position of the su bsteps follows the structure of a ''devil's staircase'', and their app earance depends strongly on the externally applied dc magnetic field.
