'Fast Exchange' model visualized with 3He confined in aerogel: a Fermi liquid in contact with a Ferromagnetic solid
Résumé
3He confined in aerogel in the millikelvin temperature domain exemplifies a Fermi liquid in the presence of disorder. In confined 3He systems, a solid layer of 3He atoms forms on the confining medium. This system can then be viewed as a model system for the study of the (strongly interacting) Fermi liquid in contact with a (ferromagnetic) "2D-like" adsorbed solid. This interaction, studied experimentally through NMR T2 experiments, is described in the framework of the "fast exchange" model. A complete analytical descripion of the model is given, explaining our measurements as well as related normal-state confined 3He NMR literature.
