Abstract

The phase stability and the electrical properties of $La(Ni_{1-x}Cu_x)O_3$ (X=0.2, 0.4, 0.6, 0.8) have been investigated. The single phases were observed in the compositions of X=0.2, 0.4, and these single phases were stable up to $870^{\circ}C$ and $950^{\circ}C$ respectively. The electrical properties of these single phase samples showed metallic behavior similar to LaNiO3 from room temperature to the temperature at which the phase was stable.
