Magneto-infrared spectroscopy, magnetization, and lattice dynamics calculations were used to explore the phase transitions in multiferroic [(CH3)2NH2]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 in this system that is much simpler than the coupling in rare earth manganites.
