Title: Effect of magnesium addition on structural and magnetic properties of NiO, Co{sub 3}O{sub 4} nanoparticles

Magnesium added NiO and Co{sub 3}O{sub 4} nanoparticles were prepared from microwave assisted method. The cubic phase natures of NiO, Co{sub 3}O{sub 4} nanoparticles have been ascertained from X-ray diffraction. XRD pattern reveals the size of the particles was reduced to quantum level for NiO than Co{sub 3}O{sub 4} due to the addition of magnesium ion. FTIR spectra have been performed to identify the vibration peaks of metal oxygen. Room temperature magnetic measurement ensures small ferromagnetic nature for Mg added NiO with higher saturation magnetization. superparamagnetic nature was examined for Mg added Co{sub 3}O{sub 4} nanoparticles.
