Abstract

In this study, synthesis and characterisation of magnesium-substituted Ni–Fe nanoparticles using microwave combustion are carried out. Using Schererr’s formula, the crystal size of the synthesised magnesium-substituted Ni–Fe nanoparticles is determined, which falls between 18 and 32 nm. Additionally, agglomerative spherical-shaped nanoparticles have been observed by high-resolution scanning electron microscopy investigation, and energy-dispersive X-ray spectroscopy is used to determine the elemental composition of Mg, Ni, Fe, and O. With the aid of diffuse reflectance spectroscopy, band gap values for the produced samples are determined to fall between 3.35 and 2.32 eV. Metal–oxygen tetrahedral sites are represented by the absorption band at 583 cm−1, while octahedral sites are linked to the absorption bands at 436 and 457 cm−1. The nickel ferrite nanoparticles being replaced with magnesium show ferromagnetic hysteresis curves.
