Abstract
The elementary pinning force on a single Abrikosov vortex trapped in a superconducting Nb thin film was measured and found to be on the order of 10- 14 N, or an average force per unit length of the vortex of 10 -8 N/m, at 8.95 K. In a cross-strip superconductor/normal-metal/ insulator/superconductor(S/N/I/S) Josephson junction a single Abrikosov vortex can be nucleated and systematically moved from one pinning site to another by using the current through one superconducting electrode. The position of the vortex within the junction is determined from the distorted shape of the Fraunhofer pattern.
