Abstract

Chromium doped NiCuZn ferrites were prepared by the sol-gel auto-combustion method. The precursors sintered at 500°C. The elemental stoichiometry determined by energy dispersive analysis of X-ray (EDAX). XRD revealed that all samples possess single cubic spinel structure. Infrared spectra were carried out at room temperature in the range of 200–800 cm−1. The IR spectra show two major absorption bands assigned to the tetrahedral and the octahedral complex. The force constants corresponding to the tetrahedral and octahedral complexes increases while RA, and RB decreases with chromium content x. The microstructures of the prepared samples were studied by SEM and TEM. Force constant for the tetrahedral and octahedral site was calculated by using IR data. The stiffness constants (C11 and C12) calculated from force constant and lattice constant. Elastic moduli and Debye temperature were determined using the values of stiffness constants, increased with chromium substitution.
