Suppression of magnetic flux avalanches and recovery of the critical state in superconducting NbN films
V. V. Yurchenko, A. J. Qviller, S. Chaudhuri +4
Thermo-magnetic instability (TMI) in superconductors is known to destroy the critical state via magnetic flux avalanches, and hence it deteriorates the ability of the superconducto…
Mechanism for flux guidance by micrometric antidot arrays in superconducting films
J. I. Vestgarden, V. V. Yurchenko, R. Wordenweber +1
A study of magnetic flux penetration in a superconducting film patterned with arrays of micron sized antidots (microholes) is reported. Magneto-optical imaging (MOI) of a YBCO film…
Very strong intrinsic supercurrent carrying ability and vortex avalanches in (Ba,K)Fe2As2 superconducting single crystals
Xiao-Lin Wang, S. R. Ghorbani, Sung-Ik Lee +9
We report that single crystals of (Ba,K)Fe2As2 with Tc = 32 K have a pinning potential, U0, as high as 10^4 K, with U0 showing very little field depend-ence. In addition, the (Ba,K…
Reentrant stability of superconducting films
V. V. Yurchenko, D. V. Shantsev, M. R. Nevala +4
We propose a mechanism responsible for the abrupt vanishing of the dendritic flux instability found in many superconducting films when an increasing magnetic field is applied. The…
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…
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…
