Effect of Fe doping on properties of Pr0.67Ba0.33Mn1-xFexO3 perovskites

Abstract

Changes in the physical properties of ceramic Pr0.67Ba0.33Mn1-xFexO3 (0 ≤ x ≤ 0.15) are interpreted as resulting from the suppression of the ferromagnetic double exchange interaction with almost no lattice effect due to similar ionic radii value of Fe3+ and Mn3+ Magnetization and transport measurements show at low temperature ferromagnetic and metallic behavior for x=0 and 0.05 samples, whereas x = 0.10 and x = 0.15 compounds show spin glass like and semiconducting behavior. At high temperature semiconductor and paramagnetic behavior are observed for all the samples.
