Abstract

Multiferroic CoFe2O4–Pb(Zr0.3,Ti0.7)O3 (CFO–PZT) nanofibers (NFs) were fabricated by the electrospinning from a mixture of PVP/ions precursor solution. CFO and PZT nanocrystals random stacked along the NF. Microstructure observations reveal that the PZT nanocrystal is surrounded by CFO nanocrystals and vice versa, which result in the disconnected spatial distribution of the piezoelectric coefficient (d33). Ferromagnetism and ferroelectricity are demonstrated by magnetic hysteresis loops and amplitude–voltage butterfly curve, respectively. Local piezoelectricity cannot represents the whole piezoelectricity of a multiferroic composite NF because it changes near the ferromagnetic crystals. This performance allows further understanding of the strain transformation between each phase in multiferroic composite NFs.
