Dendritic flux patterns in MgB2 films
T. H. Johansen, M. Baziljevich, D. V. Shantsev +7
Magneto-opitcal studies of a c-oriented epitaxial MgB2 film with critical current density 10^7 A/cm^2 demonstrate a breakdown of the critical state at temperatures below 10 K [cond…
Scaling and exact solutions for the flux creep problem in a slab superconductor
D. V. Shantsev, Y. M. Galperin, T. H. Johansen
The flux creep problem for a superconductor slab placed in a constant or time-dependent magnetic field is considered. Logarithmic dependence of the activation energy on the current…
Superconductor strip with transport current: Magneto-optical study of current distribution and its relaxation
A. V. Bobyl, D. V. Shantsev, Y. M. Galperin +3
The dynamics of magnetic flux distributions across a YBaCuO strip carrying transport current is measured using magneto-optical imaging at 20 K. The current is applied in pulses of…
