Abstract
The Ni0.45 Zn0.55-xMgxFe2O4 (x = 0.0, 0.1, 0.2 and 0.3) nanoferrites were synthesized by the sucrose method. The prepared nanoferrites were characterized by XRD, TEM, FTIR and Raman techniques. The XRD studies verified the cubic spinel-type structure of the samples. The lattice constant, particle size, bond lengths, X-ray density were determined. The lattice constant decreased as Magnesium content increased. The SAED image shows a ring pattern that establishes polycrystalline state of ferrites. The TEM image reveals a spherical shape of nanoferrite particles. The elastic parameters were calculated for obtained nanoferrites using FTIR data. The moduli of elasticity and Debye temperature decreased with increase in Magnesium content. Five first order Raman active modes were revealed by Raman Spectroscopy.
