Nanocomposite particles SrFe12O19/ CoFe2O4 were synthesized by sol-gel method. The nanocomposites are formed at the calcining temperature around 850 oC in 5 hours. The phase composition, surface morphology and magnetic properties of the nanocomposites were investigated using XRD, SEM and VSM, respectively. | Structure and magnetic properties of SrFe12O19/CoFe2O4 nanocomposite ferrite
