The as-deposited NWs are parallel to one another and exhibit a high geometrical aspect ratio. The crystal structure of these NWs shows a strong dependence on the applied deposition potential during synthesis. X-ray diffraction indicates the predominance of hexagonal-closed-packed (HCP) phase with (002) texture at low applied deposition potentials, whereas a reorientation of the c-axis of the HCP structure is observed for high electrodeposition potentials. Moreover, for a given electrodeposition time, the length of the NWs also increases with the applied potential. As a result of these structural changes, a switch in the magnetic easy axis, from parallel to perpendicular to the NW axis, occurs depending on the applied potential. A simplified model is used to account for this reorientation of the effective magnetic anisotropy direction, which takes into account the interplay between shape anisotropy, magnetocrystalline anisotropy and interwire dipolar interactions. {\^A}{\copyright} 2016 The Royal Society of Chemistry.}, url = {https://www.scopus.com/inward/record.uri?eid=2-s2.0-84957556480&doi=10.1039\%2fc6ra01311b&partnerID=40&md5=1298451596dd2ebfdf44aef920046789}, issn = {20462069}, keywords = {Anisotropy; Anodic oxidation; Aspect ratio; Cobalt; Crystallography; Deposition; Electrodeposition; Electrodes; Magnetic anisotropy; Magnetism; Magnetocrystalline anisotropy; Nanowires; X ray diffraction, Anodized aluminium oxides; Crystallographic structure; Deposition potential; Dipolar interaction; Effective magnetic anisotropy; Electrodeposition potential; Geometrical aspects; Hexagonal closed packed (hcp), Crystal structure}, author = {Irshad, M.
