摘要：
In this article we have observed the exchange spring behavior in the soft (Co0.6Zn0.4Fe2O4) hard (SrFe10.5O16.75) ferrite nanocomposites by tailoring the particle size of the individual phases and by suitable thermal treatment of the composites. Two phases were prepared with sol gel method and under appropriate stoichiometry that improved magnetic properties of these two phases. XRD analysis indicates formation of pure phase for each hard, soft and nanocomposite magnetic phases. The magnetization curves for the nanocomposites heated at different temperatures show the presence of exchange spring behavior in the composite heated at 800 degrees C and an enhancement of 53% in (BH)(max) compared to the parent hard ferrite (SrFe10.5O16.75).
