Figure 2
(a) MFM image of a head-to-head domain wall in a 1 μm wide, 80 nm thick Py strip. (b) Predicted angle θ for different width of a 80 nm thick Py strip (yellow dots). The dashed line is an extrapolation of the θ decrease as the width of the strip becomes larger. The purple squares are experimental data points deduced from the MFM images of 80 nm thick Py strips. (c) Extended phase diagram of Py strips showing the regions where the TW, asymmetric TW (ATW), VW and Landau DW have the lowest energy. The red and black data points are reproduced from Ref. 7.
