Sr 2 Ti 7 O 14 , a new phase, is synthesized by leveraging the innate chemical and thermodynamic instabilities in the SrTiO 3 –TiO 2 system and non‐equilibrium growth techniques. The chemical composition, epitaxial relationships, and orientation play roles in the formation of this novel layered phase, which, in turn, possesses unusual charge ordering, anti‐ferromagnetic ordering, and low, glass‐like thermal conductivity.
