Non-Gaussian dephasing in flux qubits due to 1/f-noise
Y. M. Galperin, B. L. Altshuler, J. Bergli +2
Recent experiments by F. Yoshihara et al. [Phys. Rev. Lett. 97, 167001 (2006)] and by K. Kakuyanagi et al. (cond-mat/0609564) provided information on decoherence of the echo signal…
Flux Dendrites of Opposite Polarity in Superconducting MgB rings observed with magneto-optical imaging
Age Andreas Falnes Olsen, Tom Henning Johansen, Daniel Shantsev +4
Magneto-optical imaging was used to observe flux dendrites with opposite polarities simultaneously penetrate superconducting, ring-shaped MgB films. By applying a perpendicular…
Magneto-optical investigations of Ag-sheathed Bi-2223 tapes with ferromagnetic shielding
V. V. Yurchenko, D. V. Shantsev, Y. M. Galperin +3
An increase in the critical current and suppression of AC losses in superconducting wires and tapes with soft magnetic sheath have been predicted theoretically and confirmed experi…
Dramatic role of critical current anisotropy on flux avalanches in MgB2 films
J. Albrecht, A. T. Matveev, J. Strempfer +4
Anisotropic penetration of magnetic flux in MgB2 films grown on vicinal sapphire substrates is investigated using magneto-optical imaging. Regular penetration above 10 K proceeds m…
Collapse of the critical state in superconducting niobium
Ruslan Prozorov, Daniel V. Shantsev, Roman G. Mints
Giant abrupt changes in the magnetic flux distribution in niobium foils were studied by using magneto-optical visualization, thermal and magnetic measurements. Uniform flux jumps a…
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…
