Abstract

Non-Fermi liquid behaviour in single-crystalline U2Pt2In has been studied by means of resistivity experiments (I parallel c) under hydrostatic pressure (P<1.5 GPa). At ambient pressure the resistivity ρ(T) follows a power law ρ to approximately Tα with α to approximately 0.5. Upon applying pressure α increases. For P>1 GPa a minimum develops in ρ(T). A study of the field dependence of the minimum confirms its magnetic origin. The ratio c/a is proposed as the effective control parameter, rather than the unit cell volume.
