Abstract

Single crystal synthesis, structure, electric polarization, and heat capacity measurements on hexagonal InMnO₃ show that this small R ion in the RMnO₃ series is ferroelectric (space group P6₃cm). Structural analysis of this system reveals a high degree of order within the MnO₅ polyhedra but significant distortions in the R-O bond distributions compared to the previously studied materials. Point-charge estimates of the electric polarization yield an electrical polarization of ∼7.8 μC/cm², 26 larger than the well-studied YMnO₃ system. This system with enhanced room temperature polarization values may serve as a possible replacement for YMnO₃ in device applications.
