Template synthesis of BaFe12O19 ordered nanowire arrays by a new method

A method that the precursor is generated in situ and shaped into the one dimension nanostructure in the nanochannels of the anodic alumina membrane (AAM) template is described. The high-aspect ratio nanowire array of the BaFe12O19 was prepared by means of this method. Electron microscope images showed that the BaFe12O19 nanowire array was abundant, uniformly distributed and well-ordered in the large area. It is estimated from the electron microscope images that the diameter of the individual nanowire is about 60 nm and the length was corresponding to the thickness of the applied AAM template. The analysis of X-ray diffraction demonstrated that the BaFe12O19 nanowires have a hexagonal structure of the pure phase BaFe12O19. (C) 2005 Springer Science + Business Media, Inc.
