Nickel-zinc ferrite (Ni0.7Zn0.3Fe2O4) nanoparticles were successfully synthesized via an environmentally friendly sol–gel combustion method employing Ginger extract as a green bio-fuel. The structural properties of the synthesized Ni0.7Zn0.3Fe2O4 nanoparticles were systematically investigated using X-ray diffraction (XRD). The diffraction patterns confirmed the formation of a single-phase cubic spinel structure with good crystallinity and no detectable secondary phases. The average crystallite size was initially estimated using the Debye–Scherrer equation, which is 12.22 nm. To further evaluate microstructural parameters. The Williamson–Hall (W–H) plot method was employed to distinguish the contributions of crystallite size and lattice strain to peak broadening. The W–H analysis revealed the presence of microstrain within the lattice along with nanoscale crystallite dimensions. The results showed excellent agreement between observed and calculated patterns, confirming the high phase purity and structural stability of the synthesized nanoparticles. The study demonstrates that ginger-assisted green combustion synthesis is an efficient method for producing structurally well-defined nickel-zinc ferrite nanoparticles suitable for advanced functional applications.
