Universidad de Zaragoza (orcid)0000-0002-3309-5961 Effects of laser-induced periodic surface structures on the superconducting properties of Niobium 2020 It is well known that the use of ultrashort (fs) pulsed lasers can induce the generation of (quasi-) periodic nanostructures (LIPSS, ripples) on the surface of many materials. Such nanostructures have also been observed in sample''s surfaces irradiated with UV lasers with a pulse duration of 300 ps. In this work, we compare the characteristics of these nanostructures on 1-mm and on 25-µm thick niobium sheets induced by 30 fs n-IR and 300 ps UV pulsed lasers. In addition to conventional continuous or burst mode processing configurations, two-dimensional laser beam and line scanning modes have been investigated in this work. The latter allows the processing of large areas with a more uniform distribution of nanostructures at the surface. The influence of the generated nanostructures on the superconducting properties of niobium has also been explored. For this aim, magnetic hysteresis loops have been measured at different cryogenic temperatures to analyse how these laser treatments affect the flux pinning behaviour and, in consequence, the superconductor''s critical current values. It was observed that laser treatments are able to modify the superconducting properties of niobium samples. © 2019 The Author(s) Access copy available to the general public Unrestricted info:eu-repo/grantAgreement/ES/DGA/T54-17R info:eu-repo/grantAgreement/ES/MINECO/ENE2017-83669-C4-1-R info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 6.707 2020 CHEMISTRY, PHYSICAL 37 / 162 = 0.228 2020 Q1 T1 PHYSICS, CONDENSED MATTER 16 / 69 = 0.232 2020 Q1 T1 PHYSICS, APPLIED 30 / 160 = 0.188 2020 Q1 T1 MATERIALS SCIENCE, COATINGS & FILMS 1 / 21 = 0.048 2020 Q1 T1 1.294 2020 Chemistry (miscellaneous) 2020 Q1 Condensed Matter Physics 2020 Q1 Surfaces, Coatings and Films 2020 Q1 Surfaces and Interfaces 2020 Q1 Physics and Astronomy (miscellaneous) 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Martínez, E.
