A Simple and Effective Synthesis of Nanosized ZnFe2O4 Particles

Abstract

Nanosized spinel zinc ferrite (ZnFe₂O₄) has been synthesized by precipitation method and characterized by using XRD, TEM and magnetic measurements techniques. XRD studies show that zinc ferrite was formed as spinel ZnFe2O4. Magnetic measurements showed that ZnFe₂O₄ is super paramagnetic in nature at room temperature and hence can be used in magnetic devices. TEM images of as synthesized ZnFe₂O₄ show that the size of particles of ZnFe₂O₄ varied from 10-30 nm which is in good agreement of the theoretically predicted size of nanomaterials. This method is convenient, easy and effective in comparison to the known methods of the synthesis of ZnFe₂O₄ nanomaterials like ultrasonic radiation, sol-gel approach, Fe implantation, thermal decomposition of metal-surfactant complexes, colloid mill, mechanical milling.
