“…These features make these materials suitable for applications such as gas sensors, [ 1 ] high‐density digital recording, magnetic resonance imaging, high electrical resistance, and resistive switching memories, and so on. [ 1–6 ] Spinel ferrite nanostructure exhibit different chemical and physical properties when compared with bulk material because of the difference in the surface area. [ 7,8 ] The cubic spinel (AB 2 O 4 ) structure exists in normal, mixed, and inverse structure depending on ion distribution on subsides.…”

Utilizing L‐arginine as a fuel, Mg1‐xSrxFe2O4 (0 ≤ x ≤ 0.5) spinel nanoparticles were prepared by the microwave combustion process. Impact of Sr2+ ion substitution on structural, morphology, optical, thermal, and magnetic characteristics is investigated by following techniques such as X‐ray diffraction (XRD), HR‐SEM, energy dispersive X‐ray analysis (EDX), diffused reflectance spectroscopy‐Ultra Violet (DRS‐UV), TG‐DTA, and VSM. XRD ensures the formation of the cubic spinel structure, and the average crystallite size was determined utilizing the Debye Scherer equation, which was found to be lying between 33.10 and 24.11 nm. HR‐SEM images exhibited agglomerated morphology, and the samples were observed to be highly crystalline in nature. EDX spectra confirmed the formation of pure and strontium doped magnesium ferrite, ensuring the existence of all the elements. The bandgap was observed to lie in between 2.02 and 1.57 eV, respectively. TG‐DTA spectra provide information regarding the total weight loss, endothermic, and exothermic transitions. From M‐H loops, it is observed that pure and strontium doped magnesium ferrite exhibits ferromagnetic behavior.
