我们报道了通过静电纺丝技术合成铁酸镍纳米纤维，特别是使用乙酸铁 (II) 作为铁前体。采用适当制备的溶液和煅烧条件，成功合成了直径均匀为～90 nm的单相镍铁氧体纳米纤维。通过静电纺丝合成的单个镍铁氧体纳米纤维由直径约 20 nm 的纳米颗粒组成。此外，在磁化测量中观察到的磁滞现象证实了它们的铁磁性，支持了它们在磁性设备中的潜在用途。这些结果表明，使用乙酸铁（II）作为铁前体是合成铁磁性镍铁氧体纳米纤维的另一种方法。
We report the synthesis of nickel ferrite nanofibers via an elecrospinning technique particularly using iron (II) acetate as an iron precursor. Nanofibers of a single-phase nickel ferrite with a uniform diameter of ∼90 nm were successfully synthesized by adopting a properly prepared solution and calcination condition. Individual nickel ferrite nanofibers synthesized by electrospinning were made up of nanograins of ∼20 nm in diameter. In addition, the hysteresis observed in a magnetization measurement confirmed their ferromagnetism, supporting their potential use in magnetic devices. These results demonstrate that the use of iron (II) acetate as an iron precursor is another way to synthesize ferromagnetic nickel ferrite nanofibers.
