Abstract:
The Mn-Zn ferrite with a composition of Mn۰.۲۵Mg۰.۰۸Cu۰.۲۵Zn۰.۴۲Fe۲O۴ has been synthesized in this study using the chemical sol-gel technique at a pH of ۷. The sample was prepared and subsequently annealed at a temperature of ۷۰۰°C. The nanocrystalline ferrite samples were subjected to characterization using X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), Thermogravimetry (TG), and Differential thermal analysis (DTA). The findings of these observations are delineated and deliberated. The sample's phase composition was verified using X-ray diffraction examination. The crystalline size was determined using Scherrer's formula and was observed to be within the range of ۲۰-۷۵ nm. Two notable stretching bands were seen in the FTIR spectra within the range of ۴۰۰-۶۵۰ cm-۱. The spinel structure of the produced nanoparticles was confirmed by these two bands. The magnetic characteristics of the powder were examined using a Vibrating Sample Magnetometer (VSM). The presence of M-H hysteresis loops suggests that the produced nanoparticles have superparamagnetic properties, as evidenced by their low coercive force, remanent magnetization, and saturation magnetization values.
