Inducing ferroelectricity in NH $_{4}$ I and NH $_{4}$ Br via partial replacement of protons by deuterons

Miao Miao Zhao, Lei Meng, Yi Yang Xu +2

While all of the polymorphs of NH $_{4}$ I and NH $_{4}$ Br are non-polar, a reversible electric polarization is established in the ordered $I^^{3}$ phases of (NH $_{4}$ ) $_{0.73}$ (ND $_{4}$ )$_{0.27}…
