Times Cited Count：43 Percentile：88.96(Multidisciplinary Sciences)We show that the electric field (EF) can control the magnetic domain wall (DW) velocity in a Pt/Co/Pd asymmetric structure. With the application of a gate voltage, a significant change in DW velocity up to 50 m/s is observed, which is much greater than that observed in previous studies. Moreover, a DW velocity exceeding 100 m/s is clearly modulated. An EF-induced change in the interfacial Dzyaloshinskii-Moriya interaction (DMI) up to several percent is found to be the origin of the velocity modulation. The DMI-mediated velocity change shown here is a fundamentally different mechanism from that caused by EF-induced anisotropy modulation. Our results will pave the way for the electrical manipulation of spin structures and dynamics via DMI control, which can enhance the performance of spintronic devices.

P with the cubic crystal structure. The ferromagnetic ordering at 
,=,3.1 K, a small saturation moment of 1.3 
/U, together with the temperature dependence of the magnetic susceptibility, are found to be well explained by considering the 5
crystalline electric field schemes for 
site symmetry and the magnetic exchange interaction.
