Original Abstract

In this paper, CoFe2−xPrxO4 (x = 0.00 to 0.1 in step of 0.025) nanoparticles were synthesized by starch-assisted sol–gel auto-combustion method. Powder Xray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Raman spectroscopy, infrared spectroscopy and vibrating sample magnetometer (VSM) were employed to characterize these synthesized CoFe2−xPrxO4 nanoparticles. The structural phase purity, crystallite size, and lattice parameter of synthesized CoFe2−xPrxO4 ferrite nanoparticles were estimated from X-ray diffraction studies. XRD patterns reveal the formation of cubic spinel ferrite with the signature of PrFeO3 phase at higher Pr3+ concentration. FE-SEM images endorse that the synthesized nanoparticles are of spherical morphology with size in the range of 5–20 nm. Raman and Fourier transform infrared (FTIR) spectra support the formation of the spinel Co–Fe–Pr ferrite structure in the nanocrystalline form. Room temperature magnetic measurement shows increase in saturation magnetization and coercivity, from 13.96 emu g−1 (x = 0.0) to 19.34 emu g−1 (x = 0.075) and 52.30 Oe (x = 0.0) to 546.94 Oe (x = 0.075), respectively, in CoFe2−xPrxO4 nanoparticles synthesized by starch-assisted sol–gel auto-combustion method.
