Abstract We investigate the magnetic damping parameter of Fe$_{1-x}$Cr$_x$ thin films using the time-resolved magneto-optical Kerr effect technique. It is demonstrated that the overall effective damping parameter is enhanced with the increasing Cr concentration. The effective damping at high field $\alpha_{0}$ is found to be significantly enhanced when increasing the Cr concentration with the $\alpha_{0}=0.159$ in the Fe$_{45}$Cr$_{55}$ enhanced by 562% compared with that of $\alpha_{0}=0.024$ in the pure Fe film. This study provides a new approach of controlling the effective damping parameter with a desired magnitude via varying Cr composition.
