We have studied the characteristics of different metastable states in NbTi thin film deposited on sapphire substrate in a region very close to the transition temperature T $$_{c}$$ , which was estimated to be about 7.6 K in our sample. Localized diss

Using a sequence of stepped bias currents in the nanosecond range, we have studied the destruction of superconductivity in c-axis textured YBa2Cu3O7 strips of various thickness and structure (single or multi-layers). Sufficiently far from Tc, vortex

International audience; By applying nanosecond current pulses to narrow superconducting Nb strips, we have observed the induced resistive states expected for quasi 1-D transport, namely localized phase-slip centres (PSC) and hot spots (HS). The curre

The resistance induced by nanosecond pulses of electric currrent or of light has been studied in superconducting Nb and NbN thin films. Narrow bridges exhibit the features expected from quasi-1D transport, namely, localized phase-slip centers (PSC) a

In order to study dynamically the resistive states which appear as jumps in the I–V curves of narrow bridges, we have submitted YBaCuO and Nb films to nanosecond current steps and laser pulses simultaneously. In constant current feed, the distincti

In addition to the critical current Ic (T), which generates Phase-Slip Centers (PSCs), thin superconducting films possess a well-defined second limiting current Ih, or current intensity able to maintain a preestablished hot spot. By pulsing step func

In narrow YBa2Cu3O7 films, we have measured the delay time between the excitation by a critical current pulse and the voltage response, and analysed it on the basis of a time-dependent Ginzburg-Landau equation to provide the gap relaxation time. In t

We have completed a comparative study on YBaCuO/PrBaCuO/YBaCuO trilayer junctions according to the crystallographic orientation of the films used in order to determine the best orientation to get a Josephson junction working at 77 K. To this end, 100
