Colossal Dielectric Response and Electric Polarization in Lithium Nitrate

Na Du, Yan Zhao, Enting Xu +3

Lithium nitrate LiNO $_{3}$ is identified to possess a dielectric constant $ε$ ' larger than 6x10 $^{6}$ at 1 kHz in powder samples above the critical temperature $T$ $_{W}$ = 306 K. For sin…

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 $γ$ phases of (NH $_{4}$ ) $_{0.73}$ (ND $_{4}$ ) $_{0.27}$ …
