Abstract
It is rigorously proved by use of Bogoliubov's inequality that, at finite temperature, a one or two dimensional Anderson or Kondo lattice can have no spontaneous lattice or sublattice magnetization.
Résumé
Utilisant l'inégalité de Bogoliubov, nous prouvons rigoureusement qu'un réseau d'Anderson ou Kondo ne peut pas avoir d'aimantation spontanée à température finie.
