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.…
Real time magneto-optical imaging of vortices in superconductors
Paal Erik Goa, Harald Hauglin, Michael Baziljevich +3
We demonstrate here real-time imaging of individual vortices in a NbSe2 single crystal using polarized light microscopy. A new high-sensitivity magneto-optical (MO) imaging system…
Dendritic magnetic instability in superconducting MgB2 films
T. H. Johansen, M. Baziljevich, D. V. Shantsev +7
Magneto-opitcal studies of a c-oriented epitaxial MgB2 film show that below 10 K the global penetration of vortices is dominated by complex dendritic structures abruptly entering t…
Hydrodynamic Instability of the Flux-antiflux Interface in Type-II Superconductors
L. M. Fisher, P. E. Goa, M. Baziljevich +3
The macroturbulence instability observed in fluxline systems during remagnetization of superconductors is explained. It is shown that when a region with flux is invaded by antiflux…
