摘要：
We report the observations of Raman scattering of the TO phonon modes from the different layers in Dy/Y rare earth superlattices. It is found that helical phase lock-in transition at about 50 K in the Dy/Y superlattice is accompanied by the softening of TO phonons from both Dy magnetic layers and Y nonmagnetic layers.
