The aim of this work is to examine the structural, magnetic and electronic properties of two perovskite-type materials PrMnO3 and PrFeO3 and their compound PrMn1-xFexO3 (0 <x< 1). For this, we used the pseudopotential PAW method based on the Density Functional Theory (DFT).frPerovskite oxide, Electronic structure, Magnetic properties, Doping, ab initio calculationThesis
