Abstract

We report the structural and dc transport studies on LaAl1-xCoxO3 (x = 0.2, 0.5, 0.8, 1.0). LaAl1-xCoxO3 samples have been prepared by solid state reaction synthesis. P-XRD patterns refined using FullProf to get the unit cell dimensions and the Co-O bond lengths. The intermediate samples exhibited mixture of rhombohedral and monoclinic phase indicating the distorted nature. The low temperature DC transport reveals small polaron hopping conduction with increasing activation energies with decrease in Co concentration.
