A study of flux lines lattice order and critical current with time of flight small angle neutron scattering
Alain Pautrat, Annie Brulet, Charles Simon +1
Small angle neutron scattering (SANS) is an historical technique to study the flux lines lattice (FLL) in a superconductor. Structural characteristics of the FLL can be revealed, p…
Structure of the flux lines lattice in NbSe2: Equilibrium state and influence of the magnetic history
A. Pautrat, M. Aburas, Ch. Simon +5
We have performed small-angle neutron scattering (SANS) of the flux line lattice (FLL) in a Fe doped NbSe_2 sample which presents a large peak effect in the critical current. The s…
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…
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…
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…
Peak-effect and surface crystal-glass transition for surface-pinned vortex array
Bernard Placais, Norbert Lutke-Entrup, Joel Bellessa +3
We present a theoretical and experimental study of the peak effect in the surface pinning of vortices. It is associated with a sharp transition in the vortex slippage length which…
