Two-dimensional imaging of trapped magnetic flux quanta in Josephson tunnel junctions
Abstract
Using low-temperature scanning-electron microscopy we have observed, with high-spatial-resolution, magnetic flux quanta trapped in a Josephson tunnel junction. The observed influence of the trapped vortices on the distribution of the Josephson current density agrees well with theoretical calculations.
