From: Dimethylglycinium hydrogen maleate‒maleic acid, a new all-organic ferroelectric with an incommensurate phase

Fig. 7

The real (a) and imaginary (b) parts of the electric permittivity measured for selected frequencies along the polar [001] direction of [DMG]+[2MA]−, and the real part of the electric permittivity along the perpendicular directions [100] (c) and [010] (d), measured on cooling the sample. The crystallographic directions refer to those of ferroelectric phase III.
