Synthesis and characterization of multifunctional Fe3O4-ZnO nanocomposite

Pure phase pristine Fe3O4 and Fe3O4-ZnO nanocomposite were prepared via a chemical route. Mössbauer measurements confirmed the presence of pure Fe3O4 phase in the nanocomposite. PL emission of the nanocomposite has displayed strong excitonic emission in UV region. M-H measurements have shown ferrimagnetic nature of the sample. A clear difference between zero-field-cooled and field-cooled in M-T measurements has shown relaxation effect in the sample.
