Crossover from Landau Fermi liquid to non-Fermi liquid behavior: Indications from Hall measurements on CeCoIn5
We conducted Hall effect measurements on the heavy-fermion superconductor CeCoIn5 for temperatures 0.05-5 K and for pressures up to 1.2 GPa. A scaling of the magnetic field H is introduced for the differential Hall coefficient, RHd = ∂ ρxy (T, H) / ∂ H resulting in a single generic curve for RHd (H) curves obtained at different T. We argue that the peak feature apparent in this generic curve corresponds to the crossover from non-Fermi liquid to Landau Fermi liquid behavior. © 2007 Elsevier B.V. All rights reserved.
