Spin transfer torque induced domain wall oscillations in ferromagnetic nanowire with a nanoscale Dzyaloshinskii–Moriya interaction region

•Discusses the role of a restoring force from nanoscale interface-DMI (iDMI)•Oscillations of domain walls, largely influenced by magnetic parameters.•Observation of GHz range frequency over a wide range.•Possible Microwave generator design.•Potentially useful for emerging neuromorphic computing.
