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.
在高达30千巴的不同压力下，对高质量的PrNiO₃样品的电阻率进行了全面的温度扫描；结果表明，在压力P约等于13千巴时，绝缘相被完全抑制，转变为非费米液体相，在该相中，在很宽的压力范围内，电阻率的变化符合Δρ = ρ(T) - ρ(0) ≈ Tⁿ，其中n = 1.33和1.60。
