Abstract

The strongly correlated metals U2Pt2In and U3Ni3Sn4 show pronounced non-Fermi liquid (NFL) phenomena at ambient pressure. Here we review single-crystal electrical resistivity measurements under pressure (p less than or equal to 1.8 GPa) conducted to investigate the stability of the NFL phase. For tetragonal U2Pt2In (l parallel to a) we observe a rapid recovery of the Fermi-liquid T-2-term with pressure. The Fermi-liquid temperature varies as T-FL similar to p-p(c), where p(c)= 0 is a critical pressure. The analysis within the magnetotransport theory of Rosch provides evidence for the location of U2Pt2In at a p= 0 antiferromagnetic quantum critical point (QCP). In the case of cubic U3Ni3Sn4 we find T-FL similar to (p-p(c))(1/2). The analysis provides evidence for an antiferromagnetic QCP in U3Ni3Sn4 at a negative pressure p(c)= -0.04+/-0.04 GPa.
