Abstract: (Ba,Ca)(Ti,Zr)O3 solid solutions are promising lead-free piezoelectrics near their polymorphic phase boundary, which is believed to be linked to the interplay between B-site driven ferroelectricity and A-site driven ferroelectricity. Focusing on (Ba,Ca)TiO3, we support this… read more here.

DOI: 10.1103/physrevb.98.174430
Abstract: We report a spin-driven ferroelectricity below the helical spin ordering temperature in a nonoxide mineral $\mathrm{MnS}{\mathrm{b}}_{2}{\mathrm{S}}_{4}$, which crystallizes in a centrosymmetric monoclinic $\mathrm{HgB}{\mathrm{i}}_{2}{\mathrm{S}}_{4}$ structure. At $\mathrm{T}\ensuremath{\sim}25\phantom{\rule{0.16em}{0ex}}\mathrm{K}$, the dielectric constant shows an anomaly and the spontaneous… read more here.
