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…
Magnetic states and spin-glass properties in Bi0.67Ca0.33MnO3: macroscopic ac measurements and neutron scattering
M. Giot, A. Pautrat, G. Andre +3
We report on the magnetic properties of the manganite Bi_{1-x}Ca_{x}MnO_3 (x=0.33) at low temperature. The analysis of the field expansion of the ac susceptibility and the observat…
Transport and magnetic properties in YBaCo2O5.45: Focus on the high-temperature transition
A. Pautrat, P. Boullay, S. Hebert +1
The electronic transport properties and the magnetic susceptibility were measured in detail in . Close to the so-called metal-insulator transition, strong effects…
Non-linear electronic transport and anomalous resistance fluctuations in the stripes state of
A. Pautrat, F. Giovannelli, N. Poirot
We report on electronic transport measurements in . Non-Ohmic and hysteretic curves are measured for 220 . Large and non Gaussian resistance…
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…
