Dielectric and magnetic response of SrFe12O19-CoFe2O4 composites obtained by solid state reaction

- SrFe12O19-CoFe2O4 nanocomposites with exchange spring behavior are synthesized.
- The exchange coupling is optimized for hard:soft magnetic wt. ratio of 4:1.
- Dielectric response of the composites is similar to those of other ferrites.
- Dielectric and electric properties are described within the Koops model.
