Abstract
We have synthesized SmFe1-xMnxO3 (x = 0.0, 0.1, 0.2 and 0.3) by solid state reaction route in order to understand their structural, morphological and dielectric properties. X-ray diffraction (XRD) patterns confirm single phase nature and the orthorhombic crystal symmetry of our samples. The lattice parameters are determined from the PowderX software, and are found to decrease with increase in Mn concentration. Williamson-Hall-plots are used to investigate physical parameters such as strain, stress, and energy density using different models namely, uniform deformation model (UDM), uniform deformation stress model (UDSM) and uniform deformation energy density model (UDEDM). The strain, stress, energy density and crystallite size increase as the concentration of Mn increases.
