Abstract
Dc-susceptibility measurements and Raman active phonon frequencies of hexagonal DyMnO3 retrace the Mn3+ ions antiferromagnetic transition at TN ∼ 70 K and their spin reorientation at TSR ∼ 48 K. The temperature evolution of Raman active mode frequencies and their over-hardening are associated with Dy3+ and Mn3+ ion displacements below TN and with a spin–phonon coupling that involves apical oxygen.
