Caption

In the crossbar-patterned sample, various behaviors of perpendicualr field driven down-up DW motions without HX can be generated dependening on the configuration of AFM spins. DW propagations were measured in a) as-grown state with randomly distributed AFM domains, and after current injections of b) positive and c) negative currents along the vertical direction (y-axis), respectively. DW motions in the horizontal branch after injection of d) positive current and e) negative current along x-axis were also measured.
