Abstract: Here we study both static and time-resolved dynamic magnetic properties of the compensated ferrimagnet ${\mathrm{Mn}}_{2}{\mathrm{Ru}}_{x}\mathrm{Ga}$ from room temperature down to 10 K, thus crossing the magnetic compensation temperature ${T}_{M}$. The behavior is analyzed with a model of a simple collinear ferrimagnet with uniaxial anisotropy and site-specific gyromagnetic ratios. We find a maximum zero-applied-field resonance frequency of $\ensuremath{\sim}160\phantom{\rule{0.16em}{0ex}}\mathrm{GHz}$ and a low intrinsic Gilbert damping $\ensuremath{\alpha}\ensuremath{\sim}0.02$, making it a very attractive candidate for various spintronic applications.
