Angular dependent hysteresis loops and magnetic properties of the Co nanowire/InP composite. (a) Angular-dependent normalized hysteresis loops of the Co nanowires/InP membrane composite obtained by VSM measurement from α = 0° (H || z) to α = 90° (H ⊥ z); inset, high magnification of the hysteresis loops around m/ms = 0. (b) Angular dependence of the remanence squareness S and the coercivity HC. (c) Angular dependence of the differential susceptibility of the Co nanowires/InP membrane obtained by VSM measurement at α = 0° (H || z) to α = 90° (H ⊥ z).
