We employ electron paramagnetic resonance (EPR) of Mn2+ as a spin probe to study the
paraelectric–ferroelectric transition in dimethylammonium manganese formate,[(CH3) 2NH2]
Mn (CHCO2) 3,(DMMnF), which is considered a model metal–organic framework (MOF) with
a Pb-free perovskite architecture. We study the variation of the Mn2+ EPR line shape and
intensity at the X-band (∼ 9.5 GHz) over 80 to 300 K. The peaks are essentially Lorentzian,
implying electron spin exchange at frequencies greater than 9.5 GHz. On cooling, an …
