摘要：

We report here the measurements of specific heat (10 K > T > 1.5 K), thermopower (300 K > T > 4 K), electrical conductivity (300 K > T > 0.4 K) and tunneling conductance (T = 4.2 K) of the perovskite oxide metal LaNiO3. We show that this oxide metal has a fairly large electron-electron interaction which gives rise to a T1/2 correction to the conductivity for T < 2 K and a V1/2 correction to the single particle density of states near the Fermi energy. The strong interaction effects in this metal arise from the low electron diffusivity.
