Angular dependence of vortex instability in a layered superconductor: the case study of Fe(Se,Te) material
Gaia Grimaldi, Antonio Leo, Angela Nigro +4
Anisotropy effects on flux pinning and flux flow are strongly effective in cuprate as well as iron-based superconductors due to their intrinsically layered crystallographic structu…
Quenching current by flux-flow instability in iron-chalcogenides thin films
Antonio Leo, Gaia Grimaldi, Anita Guarino +8
The stability against quench is one of the main issue to be pursued in a superconducting material which should be able to perform at very high levels of current densities. Here we…
Current Induced Resistive State in Fe(Se,Te) Superconducting Nanobridges
C. Nappi, C. Camerlingo, E. Enrico +4
We study the current-voltage characteristics of Fe(Se,Te) thin films deposited on CaF substrates in form of nanostrips (width , the London penetration length). In v…
Stability mechanisms of high current transport in iron-chalcogenides superconducting films
Antonio Leo, Gaia Grimaldi, Pasquale Marra +8
The improvement in the fabrication techniques of iron-based superconductors have made these materials real competitors of high temperature superconductors and MgB. In particula…
New concept for the development of Bi-2212 wires for high field applications
Andrea Malagoli, Alessandro Leveratto, Valeria Braccini +2
The first step towards high critical currents in Bi-2212 wires was the comprehension that the supercurrent is blocked over long lengths by filament-diameter bubbles grown during th…
Competition between intrinsic and extrinsic effects in the quenching of the superconducting state in FeSeTe thin films
Antonio Leo, Pasquale Marra, Gaia Grimaldi +6
We report the first experimental observation of the quenching of the superconducting state in current-voltage characteristics of an iron-based superconductor, namely, in FeSeTe thi…
