Abstract
Mn0.8+x Zn0.2TixFe2-2xO4 where x=0.1, 0.15, 0.20 were prepared by conventional solid state reaction technique starting with AR grade MnO, ZnO, TiO2 and Fe2O3. Final sintering was done at 1150°C for 20 hours followed by slow cooling to room temperature. The sample was analyzed by X-ray Diffraction (XRD), Particle size determination, SEM and EDX. The comparison of XRD results with JCPDS files confirmed the single phase spinel structure. Scanning Electron Microscopy (SEM) studies revealed that the average grain size of samples as 10μm. EDX spectrum shows the elements of the sample. X-ray instrumental broadening analysis was used to evaluate the size and lattice strain by the Williamson-Hall Plot method.
Highlights
Ferrites are ferromagnetic semi conductors and the need for high resistivity ferrites led to the synthesis of various ferrites
Energy Dispersed X Ray Spectrograph (EDX) spectrum shows the elements of the sample
X-ray Diffraction (XRD) Spectrum for the different Titanium concentrations of the sample gave a clear idea about the maximum intensity peak shifting of different concentrations of the sample
Summary
Ferrites are ferromagnetic semi conductors and the need for high resistivity ferrites led to the synthesis of various ferrites. The influence of various substituent like Ti, Zn etc considerably change in its electrical properties[1]. Polycrystalline ferrites have very good dielectric properties [2]. Ferrites having very high dielectric constants are useful in designing good microwave devices such as isolators, circulators etc. Manganese-Zinc Ferrite Mn0.8+xZn0.2Fe2O4 in the spinel structure is a low cost material which is generally useful for microwave - devices and memory-core applications. Due to Ti substitution electrical and magnetic properties changes and have much technological merits [3,4,5]. The particle size was determined from XRD details. The EDX Spectrum gave the information on the elemental composition of the material. The particle size and strain of the material was found by Instrumental Broadening and Williamson-Hall Plot method
