Study the effect of symmetrical voltage of electrodeposition and annealing ‎temperature on magnetic properties of Fe-Sn alloy nanowires

Abstract

In this research, the Fe-Sn alloy nanowires were made by AC electrodeposition method in anodic ‎aluminum oxide (AAO). The effect of different symmetrical voltages of electrodeposition (17.5-32.5 V) ‎and annealing temperature on magnetic and structural properties of Fe-Sn nanowires were investigated. ‎The magnetic properties, morphology, element composition of materials and crystal structure of the ‎nanowires were studied by AGFM, SEM, EDX and XRD, respectively. The results showed that, coercivity ‎field (Hc) and square ratio (Sq) increases by increasing deposition voltage and also, crystallinity of the ‎nanowires and resulting their crystalline magnetic anisotropy increased, but deposition percentage of Sn ‎to Fe reduced. The Hc and Sq of prepared nanowires were increased by annealing due to increases in their ‎crystalline structure and crystalline magnetic anisotropy. The most variation in Hc and Sq were achieved ‎for prepared nanowires at 30 V.‎
