Electric　field　control　of　dynamic　spin　interactions　is　promising　to　break　through　the　limitation　of　the　magnetostatic　interaction　based　magnetoelectric　(ME)　effect.　In　this　work,　electric　field　control　of　the　two-magnon　scattering　(TMS)　effect　excited　by　in-plane　lattice　rotation　has　been　demonstrated　in　a　La(0.7)SruMnO(3)　(LSMO)/Pb(Mn2/3Nb1/3)-PbTiO3　(PMN-PT)　(011)　multiferroic　heterostructure.　Compared　with　the　conventional　strain　-mediated　ME　effect,　a　giant　enhancement　of　ME　effect　up　to　950%　at　the　TMS　critical　angle　is　precisely　determined　by　angular　resolution　of　the　ferromagnetic　resonance　(FMR)　measurement.　Particularly,　a　large　electric　field　modulation　of　magnetic　anisotropy　(464　Oe)　and　FMR　line　width　(401　Oe)　is　achieved　at　173　K.　The　electric-field-controllable　TMS　effect　and　its　correlated　ME　effect　have　been　explained　by　electric　field　modulation　of　the　planar　spin　interactions　triggered　by　spin　lattice　coupling.　The　enhancement　of　the　ME　effect　at　various　temperatures　and　spin　dynamics　control　are　promising　paradigms　for　next-generation　voltage-tunable　spintronic　devices.
