Abstract
For a simple anisotropic metal model with two open nested Fermi surfaces, it is shown that the tendency to spin density wave formation increases when a magnetic field is applied, which could lead to a series of phase transitions as functions of the field value. The results are suggested as an explanation of the phase diagram of the (TMTSF)2X compounds.
Résumé
Nous montrons que la stabilité d'un état à ondes de densité de spin d'un métal quasi unidimensionnel, à surface de Fermi ouverte, augmente sous champ magnétique. Ce phénomène peut conduire à une série de transitions sous champ. Nous suggérons que ce modèle peut être une interprétation du diagramme de phase des composés (TMTSF)2X sous champ magnétique.
