Hysteresis curves at external field parallel and perpendicular to the nanowire axis for two arrays with (a) and (b) , , and .
Experimental results for the reduced remanence, (where is the saturation magnetization) as a function of the angle (dots) and analytical expression given by , using the experimental values of the intrinsic remanence obtained from the hysteresis loops of Fig. 1 (solid line).
Experimental data for the angular dependence of coercivity in Ni nanowire arrays, with length and , , and .
Magnetization reversal modes in nanowires by coherent rotation mode and transverse reversal mode.
Coercivity for different angles between the applied magnetic field and the wire axis (from 0° to 90°).
Angular dependence of the coercive field measured experimentally and calculated analytically for Ni nanowires with 50 nm diameter.
Angular dependence of the coercivity in an isolated Ni nanowire with different values of its radius. We have considered a transverse reversal mode.
