Fig. 5 a Kerr image of device saturated in −z-direction b Injection of in-plane current reverses
magnetization in the Hall cross junction and contrast changes to dark c Nucleation and de-pinning
of multiple domain walls (DWs) in 2 μm nanowire d In-plane current pulse application to 1.5 μm
nanowire nucleates and drives a single DW f Similar magnitude of current pulse nucleates and
de-pins multiple DWs in 1.5 μm nanowire
