Dependence of planar Hall effect and transverse magnetization on prior history. a The experimental protocol: measurements were performed in identical configurations but following different prior histories. In both cases, the applied magnetic field and the measured electric field were both along the x-axis and the magnetic field was swept from −x (that is θ = π) to +x. Before the measurement, however, in one case the magnetic field was rotated from −π/2 toward π, but in another from +π/2 toward π. b The planar Hall data for the two measurements. The prior history determines the sign of the observed signal. c The difference between the two data sets shown in (b) (the symmetric component). d The sum of the two data sets shown in (b) (the asymmetric response). e The experimental protocol for measuring transverse magnetization, similar to (a). f Transverse magnetization data for the two measurements. g The difference between the two measurements in (f) (the symmetric component). h The sum of the two measurements in (f) (the asymmetric component). The closed and open symbols refer to opposite field sweep orientations, marked by solid and dotted arrows shown in (b)
