## Description

- description: 'Current-induced domain-wall motion (CIDWM) in a synthetic antiferromagnet
    is a key phenomenon for developing potential high-density-packed magnetic domain-wall
    memory with fast operation. Here, CIDWM is reported in the antiferromagnetically-coupled
    two Co layers through the Ir interlayer sandwiched by the two Pt layers: Pt/Co/Ir/Co/Pt.
    The top and bottom Pt layers play a role for generating the spin current coming
    from the spin Hall effect, which gives rise to the dual spin-orbit torque (SOT)
    acting on the perpendicular magnetizations of the Co layers. Although a simple
    argument would predict that SOTs from top and bottom Pt layers cancel each other
    out, the dual SOT nucleates a reversed magnetic domain and drives the CIDWM effectively
    at current density of the order of 1011 A m−2. This study also examines the effect
    of antisymmetric interlayer exchange coupling (AIEC) on CIDWM. A positive correlation
    between the magnitude of AIEC and the domain wall velocity is found, whereas the
    current density required for nucleating the reversed domain shows a negative correlation
    with the magnitude of AIEC. These facts suggest that the existence of AIEC improves
    the performance of CIDWM. The present results provide a new avenue to design SOT
    domain wall devices based on a synthetic antiferromagnet.'
