Fabrication, Structure, and Magnetic Properties of Highly Ordered Prussian Blue Nanowire Arrays

摘要: Highly ordered Prussian blue nanowire arrays with diameters of about 50 nm and lengths up to 4μm have been fabricated for the first time by an electrodepositing technology two-step anodizing anodic aluminum oxide films. X-ray diffraction transmission electron microscopy measurement results show that nanowires are dense, continuous, highly crystalline fcc cubic structure a = 10.14 A. The Mossbauer spectrum infrared at room temperature indicate ferric ferrocyanide:  one kind iron is Fe3+ high spin other Fe2+ low spin. Magnetic property Curie decreases as average numbers magnetic interaction neighbors reduced.
