In this work, we combined magnetoinfrared spectroscopy, magnetization, and lattice dynamics calculations to explore the phase transitions in multiferroic [ ( CH 3 ) 2 NH 2 ] Mn ( HCOO ) 3 Both the 185 K ferroelectric transition and the magnetically driven transition to the fully saturated state at 15.3 T involve the formate bending mode, direct evidence of a common connection between the two types of ferroicities and for how lattice distortions advance high-temperature magnetoelectric coupling in this system.
