Abstract

Strontium ferrite enjoys a high degree of chemical stability and is completely nontoxic which makes it ideal for a wide range of applications Magnetoplumbitetype Mtype hexagonal strontium ferrite particles were synthesized via the solgel technique employing ethylene glycol as the gel precursor The phase morphology particle diameter and magnetic properties of the prepared samples were studied using Xray diffractometry XRD scanning electron microscope SEM and a vibrating sample magnetometer VSM respectively The effect of temperature on the crystal structure morphology and magnetic studies were carried out Also the thermal decomposition of assynthesized powdered samples has been studied by thermogravimetric TG and differential thermal analysis DTA methods The optical properties were analyzed using fluorescence spectra The XRD results showed that the samples synthesized at 600°C 800°C and 1000°C were of single phase and smaller crystallite size The intensity of the emission spectra of strontium ferrite was also examined The yield percentage along with structure determination and VSM studies of the prepared samples are discussed in detail
