In this paper, we portray the simulation of continuous-wave electron spin resonance (ESR) of magnetic cobalt ferrite nanoparticles (CoFNPs) which were assembled using simple sol–gel auto-combustion synthesis and irradiated with gamma dose up to 100 kGy. An emphasis has been given for estimating the crystallite size ( t 311 ) by re-evaluating Debye–Scherrer's value with the Williamson–Hall extrapolation function (W–H plot) drawn from X-Ray Diffraction (XRD) data. Also, the lattice parameter was re-confirmed via N V s (1 / d) plots. The SEM images have supported the nanosize of the CoFNPs and the skewed histogram chart has suggested the average grain distribution range 96.18–123.49 nm ± 10. The topology of the samples was studied by the atomic force microscopy images. In the first derivative peak of ESR spectroscopy, an isotropic value, i.e. gyroscopic spitting factor (Lande's g-value), and line width (ΔHpp) were used to examine the γ-radiation damage in the investigated CoFNPs samples. The present analysis may help an individual to comprehend the innumerable intra-atomic and molecular constraints affecting the subsequent physical properties of ferrite nanoparticles.
