Narrow-band noise due to the moving vortex lattice in superconducting niobium
Alain Pautrat, Joseph Scola
We report measurements of voltage noise due to vortex motion in Niobium, a conventional low-Tc superconductor. A coherent oscillation leading to narrow band noise (NBN) is evidence…
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…
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…
Metastable states of a flux line lattice studied by transport and Small Angle Neutron Scattering
A. Pautrat, J. Scola, Ch. Simon +5
Flux Lines Lattice (FLL) states have been studied using transport measurements and Small Angle Neutron Scattering in low T materials. In Pb-In, the bulk dislocations in the FLL…
Quantitative analysis of the critical current due to vortex pinning by surface corrugation
Alain Pautrat, J. Scola, C. Goupil +6
The transport critical current of a Niobium (Nb) thick film has been measured for a large range of magnetic field. Its value and variation are quantitatively described in the frame…
