Pressure-induced non-Fermi-liquid behavior of PrNiO3.
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 P approximately equal to 13 kbar, transforming to a non-Fermi-liquid phase in which the resistivity varies as Deltarho=rho(T)-rho(0) approximately T(n) with n=1.33 and 1.60 over a broad pressure range.
