Fabrication, morphological, structural and magnetic properties of electrodeposited Fe3Pt nanowires and nanotubes

Abstract Highly ordered Fe 3 Pt nanowires (NWs) and nanotubes (NTs) embedded in anodic aluminum oxide (AAO) template have been fabricated by dc electrodeposition method. Response of heat treatment on structural and magnetic properties of the samples has been studied with and without the presence of magnetic field (1 T). X-Ray Diffraction analysis shows chemically ordered L1 2 face centered cubic (FCC) as the dominant phase for Fe 3 Pt NWs and heat treatment improves crystallinity with retained its phase. Whereas, Fe 3 Pt NTs show amorphous behavior with and without magnetic field annealing. Furthermore, magnetic properties of the samples have been investigated by vibrating sample magnetometer (VSM). Magnetic parameters of Fe 3 Pt including magnetic coercivity, saturation magnetization, squareness and shape of MH-loops have been investigated as a result of simple and MF annealing.
