22. T = 0.4. This value has been determined in earlier experiments (20). In the present experimental setup, the degree of alignment cannot be controlled and, in principle, it can be noncollinear, which might explain the discrepency between theory and experiment.
23. The in-plane or out-of-plane magnetization direction of tips coated by thin films is governed by the interface and surface anisotropy of the film material, i.e., Fe or Gd, in contact with the most densely packed W surface, i.e., W(110), which is formed at the tip apex after the thermal flash. To our experience, slight deviations from the ideal magnetization directions were frequently observed, probably caused by the local atom morphology of the tip.
