Superconducting Properties and Electron Scattering Mechanisms in a Nb Film with a Single Weak-Link Excavated by Focused Ion Beam
Marlon Ivan Valerio-Cuadros,Davi A. D. Chaves,F. Colauto,A A M Oliveira,Antonio Marcos Helgueira de Andrade,Tom H. Johansen,W.A. Ortiz,M. Motta +7 more
TL;DR: In this article, a single artificial weak link in the center of a high-quality Nb film using the focused ion beam technique was constructed and its microstructural, magnetic, and electric properties in both normal and superconducting states were studied.

Effect of Moderate Electropulsing on Nb Multiterminal Transport Bridges
S Marinković,Edward Abbey,Davi A. D. Chaves,Simon Collienne,Emile Fourneau,L. Jiang,Cai-Xia Xue,Y H Zhou,W.A. Ortiz,M. Motta,Num Nguyen,A. A. Volodin,Joris Van de Vondel,Alejandro Silhanek +13 more
TL;DR: In this article , targeted and localized material modifications produced by electropulsing of microbridges with a multiterminal configuration were investigated, and the extent of the electroannealed regions is strongly influenced by the terminal geometry.
