Abstract

This paper focuses on recent magnetotransport and magnetization measurements on unconventional metals and molecular conductors down to 350 mK and in magnetic fields up to 60 T. Measurements were performed at the National High Magnetic Field Laboratory – Los Alamos Facility. Three variants of unconventional materials will be presented. First, the magnetic field effects on the thermodynamic and magnetotransport properties of the Fermi liquid regime of the heavy Fermion compound YbNi 2B 2C. Second, we present recent investigations of the Fermiology of the pnictide compound SmSb 2 by means of Shubnikov–de Haas and de Haas–van Alphen quantum oscillations. Finally, we present recent Fermi surface measurements of κ-(ET) 2Cu[N(CN) 2]Br, the layered organic superconductor with the highest T c at ambient pressure.
