Investigation the Effect of Composition and Annealing on Electrodeposited CoxPt1- X Nanowires

June 9, 2021 Physical Science 0

By electrodepositioning highly ordered CoxPt1-x (x 0.82) magnetic nanowire arrays of 60 nm diameter into the pores of anodic aluminium oxide (AAO) templates, highly ordered CoxPt1-x (x 0.82) magnetic nanowire arrays of 60 nm diameter have been effectively produced. The electrodeposition approach was chosen because it is one of the most simple, cost-effective, and easy-to-control nanowire-making processes. Deposition potential was discovered to be an important component in controlling the composition and consequently the magnetic characteristics of nanowires. XRD analysis revealed that the as-deposited CoxPt1- x nanowires have a fcc structure with a preferred orientation of (111) or (001) along the nanowire. In contrast to the near superparamagnetic response of Pt-rich nanowires, Co-rich nanowires exhibit ferromagnetic behaviour. Because of the rise in magnetocrystalline anisotropy perpendicular to the wire axis, the effects of crystallisation cause a decrease in anisotropy along the wire axis for Co82Pt18 nanowires after annealing. Within the AAO template, segmented CoPtP/Pt multilayer nanowires are deposited in the next step of our research. Due to the creation of an ordered Co-Pt alloy phase at the interface, such multilayer nanowires are expected to have a significant anisotropy. We discovered that the deposition potential is a significant component in influencing the structure and, as a result, the magnetic characteristics of nanowires.
