Abstract

Abstract: In this work, we reported investigations on the structural, magnetic and dielectric properties of Mn doped 0.9BiFeO3 -0.1BaTiO3 multiferroic compounds. X-ray diffraction studies revealed that the materials crystallized in a pure distorted rhombohedral perovskite structure. A significant magnetization increase (reaching 0.50 emu/g) was observed for Mn - doped samples. The dielectric characterization revealed that for the un-doped sample two conductivity mechanisms are present, one starting around 177 K and other around 325 K. In the doped samples, however, one of these mechanisms was suppressed increasing the resistivity and decreasing the dielectric losses of the samples.
