We show by unbiased numerical calculations that the ferromagnetic nearest-neighbor exchange interaction stabilizes a vector spin chiral order against the quantum fluctuation in a frustrated spin-12 chain relevant to multiferroic cuprates, LiCu 2 O 2 and LiCuVO 4 . Our realistic semiclassical analyses for LiCu 2 O 2 resolve controversies on the helical magnetic structure and unveil the pseudo-Nambu-Goldstone modes as the origin of experimentally observed electromagnons.
