Pressure-temperature-magnetic field phase diagram of the molecule-based multiferroic (CH<sub>3</sub>)<sub>2</sub>NH<sub>2</sub>]Mn(HCOO)<sub>3</sub>

ORAL

Abstract

We employ high pressure susceptibility and vibration spectroscopy to reveal the properties of (CH3)2NH2]Mn(HCOO)3. Combining with prior high field work, we unveil the P-T-H phase diagram of this molecule-based multiferroic. Specifically, we focus on the behavior of the formate bending mode across the order-disorder temperature to expose the role of the formate ligand in the framework stability and symmetry.
