  A theoretical study on the interplay of frustrated skyrmion and magnons is
useful for revealing new physics and future experiments design. In this work,
we investigated the magnon-driven dynamics of frustrated skyrmion in synthetic
antiferromagnets, focusing on the effect of skyrmion precession. It is
theoretically revealed that the scattering cross section of the injected
magnons depends on the skyrmion precession, which in turn effectively modulates
the skyrmion Hall motion. Specifically, the Hall angle decreases as the
precession speed increases, which is also verified by the atomistic
micromagnetic simulations. Moreover, the precession speed and the Hall angle of
the frustrated skyrmion depending on the magnon intensity and damping constant
are simulated, demonstrating the effective suppression of the Hall motion by
the skyrmion precession. This work provides a comprehensive understanding of
the magnon-skyrmion scattering in frustrated magnets, benefiting future
spintronic and magnonic applications.
