Structure and Magnetic Properties of the n = 3 Ruddlesden-Popper Oxyfluoride La_0.5Sr_3.5Fe₃O_7.5F_2.6.

ABSTRACT: Ruddlesden-Popper (RP) compounds of the general formula (AX)(ABX₃)_n with their unique sequence of perovskite-like (ABX₃) and rock-salt-like units (AX) promise applications in diverse fields such as catalysis and superconductivity. Fluorination of RP oxides often leads to dramatic changes in the material properties, caused by differences in the atomic and electronic structure. While current research focuses on fluorination of n = 1 type RP oxides (A₂BO₄), n = 3 RP oxyfluorides have remained elusive. We present the synthesis of the first iron-based n = 3 RP oxyfluoride, La_0.5Sr_3.5Fe₃O_7.5F_2.6, which was obtained from an oxide precursor by topochemical fluor
