Nd-induced defect engineering in Ba3Fe2WO9 triple perovskite: controlling phase competition, magnetic crossover, and visible-light photocatalysis
Hexagonal triple-perovskites offer a defect-sensitive platform in which magnetism and photoactivity are tuned by the interplay among local coordination, strain, and oxygen non-stoichiometry. Here, we report the synthesis of Nd-substituted Ba3Fe2WO9via solid-state reaction and the structure–property correlations using d...
