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…
Nucleation and propagation of thermomagnetic avalanches in thin-film superconductors
J. I. Vestgården, T. H. Johansen, Y. M. Galperin
Stability of the vortex matter -- magnetic flux lines penetrating into the material -- in type-II superconductor films is crucially important for their application. If some vortice…
Dendritic flux avalanches in a superconducting MgB2 tape
Thomas Qureishy, Carlos Laliena, Elena Martínez +5
MgB2 tapes with high critical current have a significant technological potential, but can experience operational breakdown due to thermomagnetic instability. Using magneto-optical…
Bidirectional particle transport and size selective sorting of Brownian particles in a flashing spatially periodic energy landscape
Fernando Martinez-Pedrero, Helena Massana-Cid, Till Ziegler +3
We demonstrate a size sensitive experimental scheme which enables bidirectional transport and fractionation of paramagnetic colloids in a fluid medium. It is shown that two types o…
Dendritic flux avalanches in superconducting films of different thickness
J. I. Vestgarden, Y. M. Galperin, T. H. Johansen
At low temperatures the critical state in superconducting films can be unstable with respect to thermomagnetic dendritic avalanches. By numerical simulations of disk-shaped superco…
Dynamical barrier for flux penetration in a superconducting film in the flux flow state
J. I. Vestgarden, Y. M. Galperin, T. H. Johansen
The penetration of transverse magnetic flux into a thin superconducting square film in the flux flow state is considered by numerical simulation. Due to the film self-field, the go…
