a Optical micrograph of the measured mesoscopic device. Scale bar: 5 μm. Three distinct measured regions are false-colored and labeled: R1–Fe0.32(1)TaS2, R2–Fe0.42(4)NbS2 / Fe0.31(2)TaS2 and R3–Fe0.32(3)NbS2. b Field-dependent magnetoresistance (MR) and anomalous Hall resistance (RAHE) recorded in regions R1–R3. c Temperature-dependent coercive field (Hc) for R1–R3. For R1–R2, the average of Hc is obtained from both MR and RAHE measurements. Here, Hc refers to the field where MR reaches its maximum while RAHE equals zero. Conversely, for R3, Hc is determined exclusively from MR data, defining it as the field where MR exhibits its minimum (upturn). The data presented in (b, c) was obtained after the initial thermal and field cycling of the device.
