Abstract

Nanosize Co1−xZnxFe2O4 (x = 0, 0.1, 0.3, and 0.4) have been synthesized by the precursor combustion technique via autocatalytic combustion of the mixed-metal fumarato-hydrazinate precursors. A key feature of these precursors is that they decompose autocatalytically once ignited to give the monophasic nanocrystalline ferrite. This fact is confirmed by X-ray powder diffraction analysis. The thermal decomposition pattern of the precursors has been studied by thermogravimetric and differential thermal analysis. The precursors have also been characterized by FTIR and chemical analysis to fix the chemical composition. The Curie temperature (Tc) of the “as-prepared” oxide was determined by alternating current susceptibility measurements.
