N2 - Spin-torque oscillators (STOs) have tunable frequencies, low energy consumption, and high-quality factor compared to traditional oscillators. Here, we report the characteristics of nanocontact-STOs in the presence of interfacial Dzyaloshinskii–Moriya interaction (DMI) based on micromagnetic simulations. The DMI can decrease the STO frequency by about 2 GHz.
