a Schematic of p-MOKE setup for in-situ magneto-electrical transport probing. b Kerr image with the yellow dashed box indicating DW stripe and Kerr signal in d(i), red dashed box refers to the threshold region and corresponding Kerr signal in d(ii). The scale bar is 20 μm. c Major K-H Loop of the device. HRKKY refers to effective field from RKKY interaction and is equaled to 885 Oe. d Dynamic DW motion emulated LIF processes under an applied |Hz| field that partially offsets HRKKY with an effective net field of ~25 Oe. Joule heating modulated RKKY, dynamic DW motion processes are recorded at different stage as depicted in (i), the reversal characteristics of threshold region in (ii), and anomalous Hall voltage under associated applied current pulses in (iii).
