采用聚乙二醇辅助共沉淀法合成了多晶nife2o4纳米线。提出的纳米线的形成机制是通过单个纳米粒子的定向聚集。进行了x射线衍射、高分辨率扫描电镜、透射电镜、微罗曼和振动样品磁强计研究。结果表明：制备的nife2o4纳米线为多晶形式，直径为58nm；合成的纳米线具有高矫顽力的室温铁磁特性。该方法有望用于大规模合成用于磁记录的nife2o4纳米线。
Polycrystalline NiFe2O4nanowires have been synthesized by PEG assisted co-precipitation method. The formation mechanism of the nanowires proposed is by means of the orientational aggregation of individual nanoparticles. X-ray diffraction, high resolution scanning electron microscopy, transmission electron microscopy, microRaman and vibrating sample magnetometry studies were carried out. The results show that NiFe2O4nanowires were in polycrystalline form with diameter of 58nm. The synthesized nanowires show room temperature ferromagnetic property with high coercivity. This method is expected to be useful for large scale synthesis of NiFe2O4nanowires for the application of magnetic recording.
