Abstract
We report the observations of Raman scattering of the TO phonon modes from the different layers in Dy/Y rare earth superlattices. It is foun d that helical phase lock-in transition at about 50 K in the Dy/Y supe rlattice is accompanied by the softening of TO phonons from both Dy ma gnetic layers and Y nonmagnetic layers.
