The sample was prepared and subsequently annealed at a temperature of 700&deg;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&#39;s phase composition was verified using X-ray diffraction examination. The crystalline size was determined using Scherrer&#39;s formula and was observed to be within the range of 20-75 nm. Two notable stretching bands were seen in the FTIR spectra within the range of 400-650 cm^-1. 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.</span></span></span></span></span><br> &nbsp; Ferrite,sol-gel method,nanocrystalline,superparamagnetic 42 50 http://ijmse.iust.ac.ir/browse.php?a_code=A-10-5278-1&slc_lang=en&sid=1 Amit Bandekar amitbandekar78@gmail.com 1800319475328460018431 1800319475328460018431 Yes University of Mumbai, Maharashtra, India Pravin Tirmali pravintirmali@gmail.com 1800319475328460018432 1800319475328460018432 No Application Specialist, I.R.
