Time-resolved x-ray magnetic circular dichroism was used to investigate epitaxial MgO(100)/Co(2)Cr(0.6)Fe(0.4)Al and MgO(100)/Co(2)Cr(0.6)Fe(0.4)Al/Cr/CoFe films. The precessional motion of the individual sublattice magnetization, excited by continuous microwave excitation in the range 2-10 GHz, was detected by tuning the x-ray photon energy to the L(3) absorption edges of Cr, Fe and Co. The relative phase angle of the sublattice magnetization's response is smaller than the detection limit of 2 degrees. A weakly antiferromagnetically coupled CoFe layer causes an increase in the ferromagnetic resonance linewidth consisting of a constant offset and a component linearly increasing with frequency that we partly attribute to non-local damping due to spin pumping.
