We calculate the vortex gyration in a nanodisk with existence of Dzyaloshinskii–Moriya interactions (DMI), including bulk DMI (BDMI) and interfacial DMI (IDMI). By analyzing the system energies, we establish quantitative relations between the gyration frequency and the magnetostatic, DMI, exchange, and Zeeman energies. Accordingly, we explain how the BDMI and IDMI alter the vortex gyration frequency in a nanodisk.
