Co₂MnGa is a magnetic Weyl semimetal with strong potential for spintronic and high-frequency device applications. Understanding its magnetization dynamics is essential for reliable device performance. Despite its potential, Co₂MnGa thin films face significant hurdles due to the high energy demands and the difficulty of growing high-quality thin-film heterostructures with clean interfaces. In this study, we performed in-plane ferromagnetic resonance (FMR) measurements on Co₂MnGa films grown on the three different substrates MgO, SiO2 and LiNbO3 (LNBO) to address the effect of substrate choice on its film growth and magnetization dynamics. The frequency dependence of the resonance field and linewidth reveals how substrate selection influences the magnetic damping accordingly.
