Synthesis and magnetic properties of ordered barium ferrite nanowire arrays in AAO template

► Synthesizing BaFe12O19 nanowire arrays by sol-gel and SHS techniques. ► Obvious magnetic anisotropy with the easy magnetizing axis parallel to the arrays. ► One dimension nanostructure in the nanochannels of the AAO template. ► Near by 11.6 GHz the electromagnetic properties of the arrays are excellent.
