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-USManganitesOptical latticesFerromagnetic ferroelectricsInfrared-active phononMagnetoelectric couplingsMagnetoelectricsMediated interactionOptical phononsOptical strainOrder parameterSpin lattice couplingSpin-phonon couplingPhononsArticlehttps://link.aps.org/doi/10.1103/PhysRevB.108.014101
