Abstract :
The M?ssbauer spectra of nanoferrite materials such as Ni0.25Mn0.75Fe2O4, Co0.5Mn0.5Fe2O4 and Ni0.4Co0.6Fe2O4 have been reported and the above materials were prepared by sol-gel combustion method using metal nitrates as source material and Polyvinyl alcohol(PVA) as agglomeration reducing agent. As the structural, thermal and magnetic properties (VSM) of the above ferrites have been published already, hence, the present paper reports the M?ssbauer studies of the nanoferrites. Based on the observed values of hyperfine parameter such as Isomer shift (IS), Quadrupole splitting (QS) and hyperfine field values, the distribution of ion and structure of the ferrites has been reported.
