While $NdNiO_{3-\delta}$ prepared ordinarily is highly oxygen-deficient and exhibits a metal-insulator transition at low temperature, it has been possible to prepare nearly metallic $NdNiO_3- \delta$ $(\delta = 0.05)$ by electrochemical oxidation. On progressive electrochemical oxidation, orthorhombic, insulating $LaMnO_3$ transforms to a rhornbohedral and then to a cubic structure. The last two phases are ferromagnetic and exhibit metal-insulator transitions.
