The activity of the group is traditionally devoted to the study of the electronic properties of strongly correlated electron systems, including heavy fermion compounds, low-dimensional organic materials and unconventional superconductors, in high magnetic fields and low temperatures. The experimental techniques include electrical transport, magnetic torque (de Haas-van Alphen effect), and specific heat measurements.
L’activité de ce groupe de recherche est traditionnellement vouée à l’étude des propriétés électroniques des systèmes fortement corrélés, y compris les composés de fermions lourds, les matériaux organiques de basse dimension et les supraconducteurs non-conventionnels, sous champs magnétiques intenses et basses températures. Les techniques expérimentales incluent le transport électronique, le couple magnétique (l’effet Haas-van Alphen), et des mesures de chaleur spécifiques. Tous les dispositifs expérimentaux sont adaptés aux champs magnétiques intenses jusqu’à 35 T produits par les aimants résistifs du laboratoire.

Left: a new frequency emerges in the Shubnikov–de Haas data in the vicinity of nc1. When the carrier density is below nc1, quantum oscillations display a single periodicity with split peaks and each peak is more prominent than its preceding neighbor
Left : a new frequency emerges in the Shubnikov–de Haas data in the vicinity of nc1. When the carrier density is below nc1, quantum oscillations display a single periodicity with split peaks and each peak is more prominent than its preceding neighbor (a).With increasing carrier density, a second frequency emerges on top of the first one (b)–(d). Data are plotted as a function of the inverse of magnetic field normalized by the principal frequency F1 in order to simplify comparison. The Fermi surface of the lower band according to Ref. [13] is shown in panel (e) and its projection along the three high-symmetry axes in panels (f) and (g). In multidomain crystals, the two possible Fermi cross sections give rise to split peaks in quantum oscillations.
