Size-dependence and high temperature stability of radial vortex magnetic textures imprinted by superconductor stray fields
D. Sanchez-Manzano, G. Orfila, A. Sander +15
Swirling spin textures, including topologically non-trivial states, such as skyrmions, chiral domain walls, and magnetic vortices, have garnered significant attention within the sc…
Numerical modelling of MgB2 conductors for high power AC transmission
F. Grilli, A. Chervyakov, V. Zermeno +4
Cables made of MgB2 superconductors are currently explored as a viable solution for transporting high electrical power in the AC regime. In order to be competitive against the DC s…
Interfilament Resistance at 77 K in Striated HTS Coated Conductors
R. Gyuráki, A. Godfrin, A. Jung +5
Striating HTS coated conductor (CC) tapes into narrow filaments offers the possibility of reducing the tapes' magnetization losses without unreasonably decreasing their current-car…
Fluorescent thermal imaging of a non-insulated pancake coil wound from high temperature superconductor tape
R. Gyuráki, T. Benkel, F. Schreiner +2
We have wound a 157-turn, non-insulated pancake coil with an outer diameter of 85 mm and we cooled it down to 77 K with a combination of conduction and gas cooling. Using high-spee…
Influence of the voltage taps position on the self-field DC and AC transport characterization of HTS superconducting tapes
M. Vojenciak, F. Grilli, A. Stenvall +2
The current-voltage (I-V) curve is the basic characteristic of a superconducting wire or tape. Measuring I-V curves is generally problematic when samples have poor stabilization. S…
3D Modeling of the Magnetization of Superconducting Rectangular-Based Bulks and Tape Stacks
M. Kapolka, V. M. R. Zermeño, S. Zou +4
In recent years, numerical models have become popular and powerful tools to investigate the electromagnetic behavior of superconductors. One domain where this advances are most nec…
