Dzyaloshinskii–Moriya interaction (DMI) and spin–orbit torque (SOT) are essential ingredients in spintronics. These effects are known to be a consequence of the inversion symmetry breaking, and main platforms for the investigation of them have been interfaces of heavy-metal/ferromagnet bilayers where the inversion symmetry are locally broken. We investigated DMI and SOT in Co/Gd/Pt ferrimagnetic multilayers in which the inversion symmetry is broken throughout whole structure.
