Importance of non-local electron correlations in BaNiS semimetal from quantum oscillations studies
Yannick Klein, Michele Casula, David Santos-Cottin +9
By means of Shubnikov-de-Haas and de-Haas-van-Alphen oscillations, and ab initio calculations, we have studied the Fermi surface of high-quality BaNiS single crystals, with mea…
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…
Peak-effect and surface crystal-glass transition for surface-pinned vortex array
B. Placais, N. Lutke-Entrup, J. Bellessa +3
The peak effect has been investigated in clean Nb crystals with artificially corrugated surfaces by measuring the linear surface impedance in the 1kHz-1MHz frequency range. From a…
rf-studies of vortex dynamics in isotropic type-II superconductors
N. Lutke-Entrup, B. Placais, P. Mathieu +1
We have measured the surface impedance of thick superconductors in the mixed state over a broad 2 kHz - 20 MHz frequency range. The depinning cross-over is observed; but it is much…
Depinning transition in type-II superconductors
N. Lutke-Entrup, B. Placais, P. Mathieu +1
The surface impedance Z(f) of conventional isotropic materials has been carefully measured for frequencies f ranging from 1 kHz to 3 MHz, allowing a detailed investigation of the d…
