Abstract
LaNi1−xCoxO3 shows itinerant d-electron behavior similar to LaNiO3 up to x=0.5. In the range 0.5<x<1.0, the cobalt spin state equilibrium is markedly affected; the localized-itinerant electron transition of LaCoO3 is not seen when x<0.95. In LaCo1−xFexO3, itinerancy of d-electrons decreases with increase in x and the compositions with x>0.5 are similar to LaFeO3. If x>0.1, the localized-itinerant electron transition is not seen and the cobalt spin state equilibrium is considerably altered. In LaNi1−xFexO3, itinerancy decreases with increase in x. These observations can be satisfactorily explained in terms of Goodenough's energy band schemes.
