A novel method to fabricate CoFe(2)O(4)/SrFe(12)O(19) composite ferrite nanofibers with enhanced exchange coupling effect

Nanocomposite of CoFe(2)O(4)/SrFe(12)O(19) has been synthesized by the electrospinning and calcination process. A novel method that cobalt powder was used to replace traditional cobalt salt in the precursor sol-gel for electrospinning was proposed. The crystal structures, morphologies, and magnetic...

description Nanocomposite of CoFe(2)O(4)/SrFe(12)O(19) has been synthesized by the electrospinning and calcination process. A novel method that cobalt powder was used to replace traditional cobalt salt in the precursor sol-gel for electrospinning was proposed. The crystal structures, morphologies, and magnetic properties of these samples have been characterized in detail. Moreover, when the average crystallite size of the hard/soft phases reached up to an optimal value, the CoFe(2)O(4) have an enhanced saturation magnetization of 62.8 emu/g and a coercivity of 2,290 Oe. Significantly, the hysteresis loops for the nanocomposites show a single-phase magnetization behavior, and it has been found that the exchange coupling interaction strongly exists in the CoFe(2)O(4)/SrFe(12)O(19) magnetic nanocomposite nanofibers.
