摘要：

We measured the resistivity rho and magnetoresistance Delta rho/rho of the metallic pseudocubic perovskite CaRuO3. At high temperatures rho = a + bT(0.5) and Delta rho/rho is negative. At low temperatures rho = a + bT(1.5) and Delta rho/rho is non-monotonic. Both at high and low temperatures rho deviates strongly from the resistivity of Fermi liquid metals, suggesting that CaRuO3 is a non-Fermi liquid metal. (C) 1999 Elsevier Science B.V.
