Structural, optical and magnetic properties of undoped NiO and Fe-doped NiO nanoparticles synthesized by wet-chemical process

Nanocrystalline nickel oxide (NiO) and ferrous doped NiO dilute magnetic nanoparticles have been prepared by wet-chemical method. The structural, composition, morphology, UV absorption and magnetic analysis of the prepared samples are characterized by XRD, FESEM, HRTEM, UV Spectra and VSM. XRD confirms the FCC phase formation. The FESEM and HRTEM used to found the structural parameters. The U-V absorption measurement shows the strong absorption at 313.24 nm and 307.9 nm for undoped NiO and Fe-doped NiO nanoparticles. The magnetic properties of these nanoparticles confirming the ferromagnetic behaviour at room temperature and has been attributed due to particle size effect.
