Quantitative magneto-optical imaging with ferrite garnets
Atle Jorstad Qviller
Magneto-optical imaging is a powerful technique for studying qualitative features of magnetic flux distributions in superconductors and other magnetic samples. However, magneto-opt…
Scaling Behavior of Quasi-One-Dimensional Vortex Avalanches in Superconducting Films
A. J. Qviller, T. Qureishy, Y. Xu +6
Scaling behaviour of dynamically driven vortex avalanches in superconducting YBaCuO films deposited on tilted crystalline substrates has been observed using qua…
Direct observation of the magnetic proximity effect in amorphous exchange-spring magnets by neutron reflectometry
A. J. Qviller, F. Magnus, B. J. Kirby +3
In this letter we report a direct observation of a magnetic proximity effect in an amorphous thin film exchange-spring magnet by the use of neutron reflectometry. The exchange-spri…
Hydrogen Concentration in Photovoltaic a-Si:H Annealed at Different Temperatures Measured by Neutron Reflectometry
A. J. Qviller, E. S. Marstein, C. C. You +5
Amorphous hydrogenated silicon (a-Si:H) is an important material for surface defect passivation of photovoltaic silicon (Si) wafers in order to reduce their recombination losses. T…
Dendritic flux avalanches in a superconducting MgB2 tape
Thomas Qureishy, Carlos Laliena, Elena Martínez +5
MgB2 tapes with high critical current have a significant technological potential, but can experience operational breakdown due to thermomagnetic instability. Using magneto-optical…
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…
