Cation, Vacancy, and Spin Ordered 15R-Superstructures in Sr(Cr1‑xFe x )O3‑y (0.4 ≤ x ≤ 0.6) Perovskites

15-layer rhombohedral (15R) SrCrO2.8-type superstructures have been discovered in Sr(Cr1‑x Fe x )O3‑y perovskites (0.4 ≤ x ≤ 0.6; space group R3̅m; a ≈ 5.56 and c ≈ 34.6 Å). Cr/Fe cations are segregated between layers of tetrahedrally and octahedrally coordinated sites. The 15R-Sr(Cr1‑x Fe x )O3‑y m...
