Abstract

Samarium and Zirconium substituted Mg-Mn ferrites having the chemical compositions Mg0.95 Mn0.05Sm2xFe2-2xO4 and Mg0.95 Mn0.05+xZrxFe2-2xO4 are prepared; where x varies 0.0 to 0.5 in steps of 0.1. These are prepared by the standard conventional ceramic method to obtain bulk size materials. Nanosize ferrites are synthesized by citrate sol-gel auto combustion method. These are characterized with X-Ray Diffraction (XRD); spectroscopic studies have been carried out by Fourier-transform Infrared Spectroscopy (FTIR) and Electron Spin Resonance (ESR) spectroscopy techniques. The observed values of nano-size materials absorption bands are compared with bulk size materials for both the substituents. Through ESR measurements, g- factor, line width, and resonance field values have been evaluated; which are interpreted based on the significant role played by the orbital angular momentum. The decrease of resonance line width shows an advantage of the materials to have power applications (cores of transformers) by resulting in low electric loss. The main objective of this paper is spectroscopic study. In future, the spectral study may play an important tool to understand and study multiferroic behavior of Sm/Zr substituted Mg-Mn ferrites.
