Description Surface magnetic state of a range of relatively thick isolated template released Ni nanowires (NW) has been thoroughly investigated. These investigations were employed using Magneto-Optical Kerr Effect (MOKE) magnetometry. The angular dependence of the switching field was accomplished by applying the magnetic field at different angles with respect to the NW long axis. All the loops showed a high squareness ratio when the magnetic field was applied parallel to the NW long axis, indicating the dominance of shape anisotropy. This result is quite different from the measurements of high density arrays of templated NW reported in literature due to the small number of nearest neighbors and hence a reduction in the magneto-static interaction amongst these NW. Square loops were noticed, at higher angles of measurements, indicating that the easy axis of magnetization might rotate with the field applied or the magnetometry detecting both transverse and longitudinal components of magnetization. The magnetization reversal of such NW is well described by the non-uniform rotation of the curling model of domain reversal. Finally, the results of this article demonstrate a difference between the surface and the bulk magnetic states which required more examinations using micro-magnetic simulations or/and magneto-transport measurements on such thick NW. Published 01 August 2018DOI: 10.14500/icpas2018.nmt49
