Abstract
Nanocrystalline ferrites MnxZn1−xFe2O4 (x = 0.0–1.0) were prepared by the combustion method without sequential heat treatment. As-synthesized MnxZn1−xFe2O4 ferrites, characterized by x-ray diffraction (XRD), have demonstrated a highly pure phase of spinel structure. From the analysis of XRD data with Scherrer’s formula, the average crystallite size is about 27–37 nm and the lattice parameters range from 8.457 to 8.515 Å. The saturated magnetization of the Mn–Zn ferrite samples, measured by vibrating sample magnetometer, is varied with the content of manganese. The high frequency electromagnetic properties were investigated by impedance spectra methods and the conduction mechanism was also discussed. The results imply that this combustion method without further thermal treatment is relatively efficient and economical as compared to conventional methods for industrial synthesis of ferrites in high frequency electromagnetic devices applications.
