a, The f dependence of dHR/dI for H along the EA ([110] and \([\bar{1}\bar{1}0]\) orientations). b, The f dependence of dHR/dI for H along the HA (\([\bar{1}10]\) and \([1\bar{1}0]\) orientations). The results in a and b are obtained for tFe = 2.8 nm. c,d, Same plots as in a and b but for tFe = 1.2 nm. Error bars in each figure (most of them are smaller than the symbol size) represent the standard error of the least squares fit of the I–HR traces in Fig. 3. The insets show the relative orientations between the current (I ∥ [100], black arrows) and the magnetic field (or magnetization), in which the EA are represented by brown arrows and the HA are represented by green arrows. e, Summary of tFe dependence of ΔHA (ΔHA = ΔHK, ΔHU, ΔHB) for opposite magnetization M directions, in which the solid symbols represent the M direction and the open symbols represent the −M direction. The inset shows the relative orientations between the charge current I and M.
