Structural And Magnetic Properties Of Mn And Zn Doped Fe[sub 3]O[sub 4] Nanoparticles

Mn and Zn doped Fe3O4 nanoparticles of size 7.36 and 12.52 nm were prepared by co precipitation method. X‐ray diffraction (XRD) pattern infers that both the samples are in single phase with Fd3m space group, which was further confirmed by Rietveld refinement. Transmission Mössbauer spectra reveals ferrimagnetic nature for Mn doping concentration while into that for Zn doping concentration it shows diamagnetic behaviour. Zn doped nanoparticles shows the superparamagnetic property.
