X-ray diffraction spectrum of the as-deposited nanowire arrays with the wire diameter of .
(a) Magnetic hysteresis loops of the nanowire arrays measured by SQUID magnetometer with magnetic field parallel and perpendicular to wire axis at . (b) The simulated loops by micromagnetic simulation with magnetic field parallel to the wire axes for different magnetocrytalline axes distribution. The solid triangles and open circles correspond to magnetocrytalline axes in fixed direction and distributes randomly in the cross section.
Angle dependence of the coercive fields for the nanowire arrays. The solid squares indicate experimental points obtained by VSM magnetometer at . The solid triangles and open circles denote the simulation results with magnetocrytalline axis in fixed direction and distributed in the cross section with the randomly azimuthal angles, respectively.
