Fig. 3: Modulated RKKY and time- and current-dependent temperature effects.

a RKKY effective field as a function of the current with RKKY effective field vs I2. The bright red shaded areas represent error bars. b The dominant Joule heating-induced field (JHIF) with a weak torque field. c Simulated temperature distribution of device with the same dimension as the experiments. d Time-dependent temperature at the center of device as highlighted in the white dashed circle of c. Inset illustrates the cross-section of temperature distribution profile along the length of device.
