Exploring the enhanced mechanical and magnetic properties of nickel-doped magnesium oxide nanoparticles

In this study, MgO nanoparticles (MNPs) and Ni-doped MgO nanoparticles (NiMNPs) were synthesized using the sol–gel method. The impact of Ni concentration on the morpho-structural, mechanical, and magnetic properties of the fabricated nanoparticles was systematically investigated. Characterization techniques including X-ray Diffraction (XRD) was employed for both MNPs and NiMNPs. XRD analysis was revealed that the synthesized samples at 600 °C exhibited a pure, single cubic phase of MNPs and also absorbed in NiMNPs. In addition to this, lattice strain (LS) and dislocation density (DD) values were calculated for further supporting the findings. As we were increasing the Ni-doping concentration (1% to 7%), the crystallite size (CS) was decreasing from 21 to 13 nm (Debye–Scherrer method) and from 23 nm to 14 nm (Hall–Williamson method), indicating a correlation between Ni concentration and structural characteristics. The mechanical and magnetic properties of the synthesized nanoparticles were thoroughly examined in this investigation.
