Skyrmion Hall effect in synthetic antiferromagnetic skyrmion bubbles vs ferromagnetic skyrmion bubbles. a The composite image of current-induced motion of SyAF skyrmion bubbles for three-pulses injection with the pulse width 1 μs. b The composite image of ferromagnetic skyrmion bubbles for three 5-μs-long pulses. Yellow arrows represent direction of displacement of skyrmion bubbles. c Schematic of the current-induced SyAF skyrmion motion in our experiment. d Skyrmion Hall angle as a function of average skyrmion velocity for synthetic antiferromagnetic (blue) and ferromagnetic (red) skyrmion bubbles. Colored range represents standard deviation
