Real spin glasses relax slowly in the shade of hierarchical trees
Eric Vincent, J. Hammann, Miguel Ocio
The Parisi solution of the mean-field spin glass has been widely accepted and celebrated. Its marginal stability in 3d and its complexity however raised the question of its relevan…
Off-equilibrium fluctuation-dissipation relation in a spin glass
Didier Herisson, Miguel Ocio
We report new experimental results obtained onthe insulating spin glass CdCrInS_4. Our experimental setup allows a quantitative comparison between thethermo-remanent magnetization…
Thermopower in the strongly overdoped region of single-layer Bi2Sr2CuO6+d superconductor
Z. Konstantinovic, G. Le Bras, A. Forget +5
The evolution of the thermoelectric power S(T) with doping, p, of single-layer Bi2Sr2CuO6+d ceramics in the strongly overdoped region is studied in detail. Analysis in term of drag…
Fluctuation-dissipation ratio of a spin glass in the aging regime
D. Herisson, M. Ocio
We present the first experimental determination of the time autocorrelation of magnetization in the non-stationary regime of a spin glass. Quantitative comparison with th…
Non-Fermi-Liquid Scaling in Ce(Ru_{0.5}Rh_{0.5})_2Si_2
Y. Tabata, D. R. Grempel, M. Ocio +2
We study the temperature and field dependence of the magnetic and transport properties of the non-Fermi-liquid compound Ce(Ru_{1-x}Rh_x)_2Si_2 at x=0.5. For fields 0.1T…
Low Field Magnetic Response of the Granular Superconductor LaSrCuO
L. Leylekian, M. Ocio, L. A. Gurevich +1
The properties of the low excitation field magnetic response of the granular high temperature (HTSC) superconductor LaSrCuO have been analyzed at low temperatures. The response of…
