Abstract

We measured the resistivity (ρ)and magnetoresistance (ρΔ/ρ) of the metallic pseudocubic perovskite CaRuO₃. At high temperatures, ρ= a+bT^0.5 and Δρ/ρ is negative. At low temperatures, ρ= a+bT^1.5 and Δρ/ρ changes sign as a function of the applied magnetic field. Both at high temperatures and at low temperatures, ρ deviates strongly from the resistivity of Fermi-liquid metals; we therefore discuss the possibility that CaRuO₃ is a non-Fermi-liquid metal.
