摘      要：We investigate the magnetic damping parameter of Fe 1−x Cr x thin films using the time-resolved magneto-optical Kerr effect *** is demonstrated that the overall effective damping parameter is enhanced with the increasing Cr *** effective damping at high fieldα0 is found to be significantly enhanced when increasing the Cr concentration with theα0=0.159 in the Fe 45 Cr 55 enhanced by 562%compared with that ofα0=0.024 in the pure Fe *** study provides a new approach of controlling the effective damping parameter with a desired magnitude via varying Cr composition.
