a Measurement schematic to obtain RA and HK. For RA extraction, the external field (Bext) direction is fixed along the Z-axis (θB = 0°) and its magnitude is swept. For HK extraction, the magnitude of Bext is fixed, while its direction is rotated in the Z–Y plane. Rω is obtained by dividing the first harmonic in phase component of the anomalous Hall voltage by the R.M.S of the AC current excitation. b Measured curves from stacks A, B and C for RA extraction. Obtained RA from the remanent values of Rω at Bext = 0 are mentioned in blue text. c Curves obtained from the rotation experiment. The fits to the measured curves give the value of HK (which are mentioned in blue text in each figure inset).
