magnetic properties - Opis:
- The influence of microwave (MW) plasma on magnetization and morphology of sol-gel synthesized MnFe2O4 ferrite nanoparticles is investigated in this study. Manganese (II) nitrate hexahydrate, ferric (III) nitrate nanohydrate and citric acid were used to synthesize ferrite nanoparticles via a facile sol-gel route. These ferrite nanostructures were heat-treated at 700ºC and then given MW plasma treatment for 10 min. The pristine MnFe2O4 and plasma treated MnFe2O4 showed almost similar structural formation with a slight increase in crystallinity on plasma treatment. However, XRD peak intensity slightly increased after plasma treatment, reflecting better crystallinity of the nanostructures. The size of the particle increased from 35 nm to 39 nm on plasma treatment. It was challenging to deduce the surface morphology of the nanoparticles since both samples were composed of a mixture of big and small clusters. Clusters that had been treated with plasma were larger in size than pristine ones. The band gap energy of the pristine MnFe2O4 sample was about 5.92 eV, which increased to 6.01 eV after treatment with MW plasma. The saturation magnetization of MnFe2O4 sample was noted about 0.78 emu/g before plasma treatment and 0.68 emu/g after MW plasma treatment.
