摘要：
We discuss the existence of fluxons in superconductor/ferromagnet/superconductor Josephson junction with external current described by an inhomogeneous double sine-Gordon equation. Based on an extended Feynman's argument, we derived the corresponding current-phase relation from the nonlinear interaction of the macroscopic wavefunctions between the two superconductors. The result shows that the only solution that survive under the presence of external current are the bright and dark fluxons, while a new type of dark fluxon with peculiar shape is found.
