Polymorphism in Bi-based perovskite oxides: a first-principles study

Akansha Singh, Viveka N. Singh, Enric Canadell +2

Under normal conditions, bulk crystals of BiScO${}_3$ , BiCrO${}_3$, BiMnO${}_3$, BiFeO${}_3$, and BiCoO${}_3$ present three very different variations of the perovskite structure: an antipol…
