NiAlxFe2-xO4 (x = 0.0-1.0 in the step of 0.2) spinet ferrite system was prepared by the co-precipitation method. The elemental compositional stoichiometry, microstructure, infrared spectral and elastic properties have been carried out by means of energy dispersive analysis of X-ray (EDAX), scanning electron microscopy (SEM) and infrared spectroscopic (IR) measurements. Infrared spectra were carried out at room temperature in the wavenumber range of 300-800 cm(-1). The IR spectra show three major absorption bands. High frequency bands 'nu(1)' is assigned to the, tetrahedral and low frequency bands 'nu(2)' is assigned to the octahedral complex. Small frequency bands 'nu(3)' is assigned to Al3+O-2 complexes. Force constant for the tetrahedral and octahedral site was determined by using IR data. Force constant used to calculate the stiffness constants (C-11 and C-12). Using the values of stiffness constants; elastic moduli such as Young's modulus, bulk modulus, modulus of rigidity, Poisson ratio and Debye temperature were calculated. (C) 2013 Elsevier B.V.
