Magnetic free energy profiles for the initial state (a) and during application of 0.1 s current pulses of 100, 250, 250, and 400 µA (b–e). Dotted vertical lines in panels (a–e) indicate the direction of the background field, and solid circles show the direction of the magnetization. Directions of magnetization are also shown in the polar plots (f–j), where dotted and solid arrows indicate directions of the magnetization before and after current pulses, respectively. PHR values measured 60 s before and after the current pulses are shown at the bottom of the panels (f–j).
