Description
Summary:CoFe2O4 nanocables have been successfully fabricated by electrospinning involving the nanoscale Kirkendall effect. The average diameters of the outer tubes and inner wires of CoFe2O4 nanocables are around 200nm and 85nm, respectively. The detailed formation process nanoscale morphology, structure and unique magnetic properties of CoFe2O4 nanocables have been studied comprehensively. Each fully calcined individual nanocable is composed of CoFe2O4 monocrystallites, which stacked along the longitudinal direction with random orientation. The coercivity (Hc) of the CoFe2O4 nanocables decreases from 11043Oe at 10K to 707Oe at 300K, and a spin reorientation has been detected at 5K and 100K, which is different from CoFe2O4 nanorods and nanoparticles. •CoFe2O4 nanocables were prepared using an electrospinning technique.•Formation mechanism of nanocables is based on the Kirkendall effect.•The CoFe2O4 nanocables have a cubic spinel structure.•The magnetic properties of the CoFe2O4 nanocables were performed.
