High frequency dielectric response and magnetic studies of Zn1−xTbxFe2O4 nanocrystalline ferrites synthesized via micro-emulsion technique

Nanocrystalline spinel ferrites (Zn1−xTbxFe2O4) prepared by micro-emulsion technique exhibited the reduced dielectric parameters and decreased crystallite size from 24 nm to 16 nm upon the doping of terbium. These ferrites revealed ferrimagnetic behavior. Larger magnetic and smaller dielectric parameters suggest the potential use of these nanomaterials in memory and high frequency devices fabrications.190
