Résumé
Abstract

Cet article se veut une présentation générale de la spintronique. C'est aujourd'hui un important domaine de recherche, qui se développe sur de nombreux nouveaux axes de la physique de la matière condensée. Nous avons voulu présenter simplement les phénomènes physiques impliqués dans la spintronique – sans équations, mais avec de nombreux schémas. Nous décrivons aussi les applications de la spintronique, celles d'aujourd'hui et celles dont l'on attend un impact important sur les prochains développements des technologies de l'information et de la communication.

This article aims at giving a general presentation of spintronics, an important field of research developing today along many new directions in physics of condensed matter. We tried to present simply the physical phenomena involved in spintronics – no equations but many schematics. We also described the applications of spintronics, those of today and those expected to have an important impact on the next developments of the information and communication technologies.
