Spin-phonon coupling and magnetoelectrical properties: EuMnO3 versus GdMnO3

Correlation between spin-phonon coupling and the magnetoelectric properties of EuMnO3 and GdMnO3 were investigated using ceramic samples in this work. The experimental results evidence a stronger spinphonon coupling in GdMnO3 than in EuMnO3, as well as a clear anomaly in the phonon contribution for...
