Abstract

Comprehensive temperature scans of the resistivity of a high-quality sample of PrNiO3 were made under different pressures up to 30 kbar; they have revealed that the insulator phase is suppressed completely at P13kbar, transforming to a non-Fermi-liquid phase in which the resistivity varies as Δρ=ρ(T)ρ0Tn with n=1.33 and 1.60 over a broad pressure range.
