Noncollinear ferroelectric and screw-type antiferroelectric phases in a metal-free hybrid molecular crystal.

ABSTRACT: Noncollinear dipole textures greatly extend the scientific merits and application perspective of ferroic materials. In fact, noncollinear spin textures have been well recognized as one of the core issues of condensed matter, e.g. cycloidal/conical magnets with multiferroicity and magnetic skyrmions with topological properties. However, the counterparts in electrical polarized materials are less studied and thus urgently needed, since electric dipoles are usually aligned collinearly in most ferroelectrics/antiferroelectrics. Molecular crystals with electric dipoles provide a rich ore to explore the noncollinear polarity. Here we report an organic salt (H₂Dabco)BrClO₄ (H₂Dabco = N,N'-1,4-diazabicyclo[2.2.2]octonium) that shows a transition between the ferroel
