Persistence of characteristics of an ordered flux line lattice above the second peak in
A. Pautrat, C. Simon, Ch. Goupil +4
We report Small Angle Neutron Scattering measurements of the flux lines lattice (FLL) in . As previously reported, the scattered intensity decreases strongl…
New Insight into the Fluctuations of the Moving Vortex Lattice: Non-Gaussian Noise and Levy Flights
J. Scola, A. Pautrat, C. Goupil +3
We report measurements and analysis of the voltage noise due the to vortex motion, performed in superconducting Niobium micro-bridges. Noise in such small systems exhibits importan…
Why pinning by surface irregularities can explain the peak effect in transport properties and neutron diffraction results in NbSe2 and Bi-2212 crystals?
Charles Simon, Alain Pautrat, Christophe Goupil +6
The existence of a peak effect in transport properties (a maximum of the critical current as function of magnetic field) is a well-known but still intriguing feature of type II sup…
Experimental study of the correlation length of critical-current fluctuations in the presence of surface disorder: Probing vortex long-range interactions
J. Scola, A. Pautrat, C. Goupil +1
We report on critical currents and voltage noise measurements in Niobium strips in the superconducting state, in the presence of a bulk vortex lattice () and in the sur…
Longitudinal and transverse noise in a moving Vortex Lattice
J. Scola, A. Pautrat, C. Goupil +1
We have studied the longitudinal and the transverse velocity fluctuations of a moving vortex lattice (VL) driven by a transport current. They exhibit both the same broad spectrum a…
On voltage-current characteristics and critical current in Bi-2212
A. Pautrat, Ch. Simon, J. Scola +5
V(I) characteristics have been performed in a monocrystalline microbridge of . The vortex phase diagram has been greatly investigated. Linear but non-ohmic Voltage(Cur…
