Here we explore the resulting coupling between structure, magnetism and electric dipoles at the 1st order tautomeric transition near 110 K. We perform measurements in DC and pulsed fields to 60 T and as a function of temperature. We investigate the bistable behavior and the dynamics of this 1st order phase transition, avalanching effects in magnetic fields and the polarization changes across the transition.
