Complete Suppression of Thermomagnetic Instabilities in Nb Superconducting Films by Combined Metallic Layers and Ion Irradiation
D. Carmo, A. M. H. de Andrade, R. Giulian +3
Thermomagnetic instabilities in superconducting films can trigger flux avalanches that disrupt the critical state and impair the performance of superconducting devices. Here we inv…
Maximum limit of connectivity in rectangular superconducting films with an oblique weak link
F. Colauto, D. Carmo, A. M. H. de Andrade +3
A method for measuring the electrical connectivity between parts of a rectangular superconductor was developed for weak links making an arbitrary angle with the long side of the sa…
Enhancing the effective critical current density in a Nb superconducting thin film by cooling in an inhomogeneous magnetic field
D. A. D. Chaves, I. M. de Araújo, D. Carmo +7
Quantitative magneto-optical imaging of a type-II superconductor thin film cooled under zero, homogeneous, and inhomogeneous applied magnetic fields, indicates that the latter proc…
Measurement of critical current flow and connectivity in systems of joined square superconducting plates
F. Colauto, D. Carmo, A. M. H. de Andrade +4
A method to measure the electrical connectivity between square superconducting plates joined by weak link interfaces is presented. It is based on observation of lines where the flo…
Nematic state in CeAuSb
S. Seo, Xiaoyu Wang, S. M. Thomas +9
At ambient pressure and zero field, tetragonal CeAuSb hosts stripe antiferromagnetic order at K. Here we first show via bulk thermodynamic probes and x-ray diff…
Active control of thermomagnetic avalanches in superconducting Nb films with tunable anisotropy
D. Carmo, F. Colauto, A. M. H. de Andrade +4
Active triggering and manipulation of ultrafast flux dynamics in superconductors are demonstrated in films of Nb. Controlled amounts of magnetic flux were injected from a point alo…
