## Description

- description: We experimentally study the magnetization dynamics of an all-in-plane
    spin-torque oscillator (AIP-STO) by using injection locking to an external microwave
    magnetic field. The AIP-STO exhibits multiple frequency signals corresponding
    not only to the oscillation frequencies of the magnetic layers but also to the
    difference between these frequencies. The oscillation frequency is identified
    based on the principle that injection locking occurs only to the signal corresponding
    to the magnetization oscillation. We also analyze the magnetization dynamics during
    injection locking by micromagnetic simulations. The results demonstrate that injection
    locking is a powerful tool for elucidating the oscillation of the AIP-STO.
