Characterization of the single crystalline iron sulfide nanowire array synthesis by pulsed electrodeposition

Magnetic material Fe7 S8 nanowire arrays have been successfully synthesized by pulsed electrodeposition in porous anodized aluminum oxide template. X-ray diffraction results show that the as-synthesized nanowires are single crystalline and have a highly preferential orientation. Scanning electron microscopy and transmission electron microscopy observations indicate that the ordered Fe7 S8 nanowire arrays are uniform with a diameter of 50 nm and length up to several tens of micrometers. The temperature variation of the magnetic properties has also been studied.
