| dc.description.abstract | We show the role of strain in magnetoelectric effect through coupling between order parameters and their interplay using infrared/Raman-active optical phonons in hexagonal manganite (h-ErMnO3). The magnetoelectric coupling is arbitrated through strain from infrared-active phonons, which by symmetry are also Raman active. The identification of the primitive order parameters by spin-phonon coupling opens a promising avenue to realize the strategy based on coupling of spins, optical phonons, and strain to create magnetoelectrics with strain-mediated interaction through spin-lattice coupling in bulk inducing a ferromagnetic-ferroelectric state in an antiferromagnetic-paraelectric phase. � 2023 American Physical Society. | en_US |
