Investigation of Structural, Electrical and Thermal Characteristics of NdFeO 3 Ceramic

The synthesis of single phase polycrystalline ceramic sample of NdFeO 3 by high temperature solid state reaction technique using high purity oxides has been reported. The structural parameters were investigated by Rietveld refinement program. The prepared ceramics show orthorhombic structure with space group Pnma. The frequency and temperature dependent dielectric constant, dielectric loss and ac conductivity of the compound have been studied. The dc conductivity has also been measured and its activation energies were calculated using Arrhenius relation. The calculated heat capacity (ΔCp) and enthalpy change (ΔH) of the compound are 0.068 J/gK and 2.3664 J/g respectively.
