Description 81-86
Nanophase zinc ferrite (ZnFe₂O₄) has been prepared by co-precipitation under stoichiometric conditions. The effect of reactant concentration on particle size has been studied using XRD, structural details using IR absorption spectroscopy, thermal properties using TG/DTA analysis and magnetic moment using SQUID magnetometer measurement. IR spectroscopy has been found to be an important tool for characterizing nanophase ZnFe₂O₄ particles size in the range 4 
28 nm. The positions of the absorption band are found to be particle size dependent. The large increase in magnetization with decrease in particle size may be due to super exchange interaction between Fe³⁺ ions on two sublattices A and B. The morphology of the sample has been investigated by TEM and selected area electron diffraction pattern.
