Interlayer Ions Control Spin Canting in Low-Dimensional Manganese Trimers in 12R-Ba₄MMn₃O₁₂ (M = Ce, Pr) Layered Perovskites.

ABSTRACT: To synthetically target a specific material with select performance, the underlying relationship between structure and function must be understood. For targeting magnetic properties, such understanding is underdeveloped for a relatively new class of layered hexagonal perovskites, the 12R-Ba₄MMn₃O₁₂ family. Here, we perform a detailed magnetostructural study of the layered hexagonal perovskite materials 12R-Ba₄MMn₃O₁₂, where M = diamagnetic Ce⁴⁺ or paramagnetic J_eff ≈ 1/2 Pr⁴⁺. The material with M = Ce⁴⁺ is an antiferromagnet below T_N ≈ 7.75 K, while the material with M = Pr⁴⁺ exhibits more complex behavior, with
