By use of optical pump-probe measurement, we study the relaxation dynamics of a multiferroic-ferromagnetic TbMnO3/La0.7Sr0.3MnO3 bilayer. The relaxation dynamics of both layers are well separated in time allowing us to investigate the magnetic coupling across the bilayer. We observe that the relaxat...
