A new approach to the inverse problem for current mapping in thin-film superconductors
J. W. Zuber, F. S. Wells, S. A. Fedoseev +3
A novel mathematical approach has been developed to complete the inversion of the Biot-Savart law in one- and two-dimensional cases from measurements of the perpendicular component…

Observation of Transient Overcritical Currents in YBCO Thin Films using High-Speed Magneto-Optical Imaging and Dynamic Current Mapping
Frederick S. Wells, Alexey V. Pan, Igor A. Golovchanskiy +2
The dynamics of transient current distributions in superconducting YBCO thin films were investigated during and immediately following an external field ramp, using high-speed (real…
