A hybrid double perovskite ferroelastic exhibiting the highest number of orientation states

abstract

Integrating NH4+ as a B & PRIME;-site ion within a three-dimensional double hybrid perovskite resulted in a novel high-temperature ferroelastic, (Me3NOH)2(NH4)[Co(CN)6], which uniquely demonstrates a reversible triclinic-to-cubic phase transition at 369 K and offers a record-setting 24 orientation states, the highest ever reported among all ferroelastics. New 3D hybrid double perovskite ferroelastic, exhibiting unique reversible phase transition, boasts record 24 orientation states, surpassing all known ferroelastics.
