Figure 3: Magnetic properties of the films.
(a,b) W thickness dependence of the volume averaged saturation magnetization M/V (a) and the magnetic anisotropy energy KEFF (b). The solid line shows linear interpolation of the data. (c,d) DW anisotropy field HK (c) and the wall width parameter Δ (d) calculated from the interpolated data shown in a and b. The symbols represent values of HK and Δ that are used in the calculations presented in Fig. 4 for 5 μm wide wires (open circles) and for 50 μm wide wires (solid square). All results are from film set A.
