Doctoral Dissertations
Due to their low energy scales, flexible architectures, and unique exchange pathways, molecule-based multiferroics host a number of unique properties and phase transitions under external stimuli. In this dissertation, we reveal the magnetic- and pressure-driven transitions in [(CH3)2NH2]Mn(HCOO)3 and (NH4)2[FeCl5(H2O)], present a detailed investigation of these materials away from standard equilibrium phases, and develop rich two- and three-dimensional phase diagrams.
The first platform for exploring phase transitions is [(CH3)2NH2]Mn(HCOO)3. This type-I multiferroic contains Mn centers linked by …
