Etude des propriétés électroniques et magnétiques des pérovskites PrFeO3 et PrMnO3 et leur composé PrMn1-xFexO3

Abstract

For several years, many studies have been carried out on oxides of the perovskite type ABO3, the latter presented a great diversity of physical properties. 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).
