(a) Dependence of PHR on field orientation observed at various currents, from 20 µA to 900 µA, as an external field of 55 Oe is rotated CCW over 360°. Black thick arrows show the direction of magnetization at different field orientations during magnetization reversal. (b) Expanded view of the region between 75° and 150°. Importantly, the direction of magnetization can be different at the same field orientation for different currents, as illustrated by the behaviour in the yellow shaded region.
