Photoconductivity and Photoemission of Diamond Under Femtosecond Vuv Irradiation

Jérôme Gaudin, Ghita Geoffroy, Stéphane Guizard +8

In order to gain some insight on the electronic relaxation mechanisms occuring in diamond under high intensity laser excitation and/or VUV excitation, we studied experimentally the…

Ferromagnetic Domain Structure of La0.78Ca0.22MnO3 Single Crystals

Grzegorz Jung, Vladimir Markovich, Kees van der Beek +2

The magneto-optical technique has been employed to observe spontaneous ferromagnetic domain structures in La0.78Ca0.22MnO3 single crystals. The magnetic domain topology was found t…

Anisotropic Magneto-Thermopower: the Contribution of Interband Relaxation

J. -E. Wegrowe, Q. Anh Nguyen, M. Al-Barki +3

Spin injection in metallic normal/ferromagnetic junctions is investigated taking into account the anisotropic magnetoresistance (AMR) occurring in the ferromagnetic layer. It is sh…

Comment on "Sound Modes broadening in Quasicrystals"

G. Coddens

Recently de Boissieu et al. proposed an explanation for the broadening of acoustic modes observed in quasicrystals (QC). It is the transcription of a well-known model used for glas…

Many-body perturbation theory using the density-functional concept: beyond the GW approximation

Fabien Bruneval, Francesco Sottile, Valerio Olevano +2

We propose an alternative formulation of Many-Body Perturbation Theory that uses the density-functional concept. Instead of the usual four-point integral equation for the polarizab…
