Synthesis and characterization of BaMnO3multiferroic ceramics

Abstract

In the present study, BaMnO3 ceramic oxide has been prepared and analysed using various experimental techniques. The proposed material has been prepared using high temperature solid state reaction route. The structural (XRD), microstructural (FESEM), compositional (EDX) and dielectric properties have been studied extensively. X-ray diffraction (XRD) analysis confirms the formation of compound. Field Emission Scanning Electron Micrograph (FESEM) shows thenon-homogenous distribution of grains ranging from 1-1.5��mwhich are densely packed. Energy Dispersive X-ray (EDX) spectroscopic analysis shows the presence of all the elemental in BaMnO3. The ferroelectric to paraelectric phase transition is observed from temperature dependent dielectric analysis. The loss tangent is found to be increases with increase in temperature. DC and AC conductivity decreases with increase in temperature
