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…

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…

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…
