Infrared Spectroscopy And Elastic Properties Of Pr3+ Ions On Doped Co-Ni Ferrite

Abstract

Spinel ferrite system Co_0.6Ni_0.4Fe_2-xPr_xO₄ (x = 0.000 to 0.100 in the step of 0.025) was prepared by sol-gel auto combustion method. The Fourier Transform Infrared Spectra (FT–IR) of the Co-Ni ferrite system have been analyzed at room temperature in between the frequency range of 200–800 cm^-1. The high-frequency absorption band ‘υ₁’ assigned to tetrahedral complex and low-frequency absorption band ‘υ₂’ assigned to octahedral complex. The force constant, bond length and Debye temperature were determined by infrared spectra analysis. The force constant, lattice constant and pore fraction have been used to investigate the elastic moduli such as Young’s Modulus, Bulk Modulus, Rigidity Modulus.
