Interaction between superconducting vortices and Bloch wall in ferrite garnet film
J. I. Vestgarden, D. V. Shantsev, A. A. F. Olsen +4
Interaction between a Bloch wall in a ferrite-garnet film and a vortex in a superconductor is analyzed in the London approximation. Equilibrium distribution of vortices formed arou…
Onset of dendritic flux avalanches in superconducting films
D. V. Denisov, D. V. Shantsev, Y. M. Galperin +7
We report a detailed comparison of experimental data and theoretical predictions for the dendritic flux instability, believed to be a generic behavior of type-II superconducting fi…
Single vortices observed as they enter NbSe
A. A. F. Olsen, H. Hauglin, T. H. Johansen +2
We observe single vortices as they penetrate the edge of a superconductor using a high-sensitivity magneto-optical microscope. The vortices leap across a gap near the edge, a dista…
Local threshold field for dendritic instability in superconducting MgB2 films
F. L. Barkov, D. V. Shantsev, T. H. Johansen +5
Using magneto-optical imaging the phenomenon of dendritic flux penetration in superconducting films was studied. Flux dendrites were abruptly formed in a 300 nm thick film of MgB2…
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…
Interaction between a magnetic domain wall and a superconductor
L. E. Helseth, P. E. Goa, H. Hauglin +2
The interaction between a magnetic thin film and a superconductor is studied. In particular, the equilibrium width of a Bloch wall is estimated with and without the superconductor.…
