Electrical detection of spin accumulation in a p-type GaAs quantum well
R. Mattana, J. -M. George, H. Jaffres +5
We report on experiments in which a spin-polarized current is injected from a ferromagnetic electrode into a quantum well through an AlAs barrier. The resulting spi…

Timescales in shear banding of wormlike micelles
O. Radulescu, P. D. Olmsted, J. P. Decruppe +3
We show the existence of three well defined time scales in the dynamics of wormlike micelles after a step between two shear rates on the stress plateau. These time scales are compa…

Dynamics of modulated and composite aperiodic crystals: the signature of the inner polarization in the neutron coherent inelastic scattering
O. Radulescu, T. Janssen, J. Etrillard
We compare within an unifying formalism the dynamical properties of modulated and composite aperiodic (incommensurate) crystals. We discuss the concept of inner polarization and we…
