摘要：

It is shown that there are two vortex states for the configuration of an Abrikosov vortex in the presence of a long Josephson junction. One state, dubbed 'conventional', carries one magnetic-flux quantum Phi(0), as does the generating Abrikosov vortex. The second and new vortex state entails in addition to the generating vortex two Josephson vortices with opposite polarity to that of the generating-vortex and its magnetic flux is -Phi(0). As a function of the vortex core and Josephson junction-plane distance, the accompanying pinning potentials are quasi-degenerate in the near proximity to the Josephson junction plane, where the conventional-vortex-state pinning potential is the lower. Conditions facilitating the experimental observation of the new vortex state and a specific signature are briefly discussed. (C) 1999 Elsevier Science B.V. All rights reserved.
