Query: Pressure-induced recovery of the Fermi-liquid state in the non-Fermi
  liquid material U2Pt2In   In the study of non-Fermi-liquid (NFL) phenomena in correlated metals,
U2Pt2In is of special interest as it is one of the rare stoichiometric
(undoped) materials that show NFL behaviour at ambient pressure. Here we report
on the stability of the NFL phase with respect to hydrostatic pressure (p< 1.8
GPa). Electrical resistivity data under pressure, taken on a single-crystalline
sample for a current in the tetragonal plane, show that T_FL, i.e. the
temperature below which the Fermi-liquid T^2-term is observed, increases with
pressure as T_FL ~ (p-p_c), where p_c~0 is a critical pressure. This provides
strong evidence for the location of U2Pt2In at an antiferromagnetic quantum
critical point.
