Diameter-Controllable Magnetic Properties of Co Nanowire Arrays by Pulsed Electrodeposition

الملخص EN

The Co nanowires with different diameters were prepared by pulsed electrodeposition into anodic alumina membranes oxide templates.

The micrographs and crystal structures of nanowires were studied by FE-SEM, TEM, and XRD.

Due to their cylindrical shape, the nanowires exhibit perpendicular anisotropy.

The coercivity and loop squareness (Mr/Ms) of Co nanowires depend strongly on the diameter.

Both coercivity and Mr/Ms decrease with increasing wire diameter.

The behavior of the nanowires is explained briefly in terms of localized magnetization reversal.
