Site-Selective d¹⁰/d⁰ Substitution in an S = ¹/₂ Spin Ladder Ba₂CuTe_1-xW_xO₆ (0 ≤ x ≤ 0.3).

ABSTRACT: Isovalent nonmagnetic d¹⁰ and d⁰ B″ cations have proven to be a powerful tool for tuning the magnetic interactions between magnetic B' cations in A₂B'B″O₆ double perovskites. Tuning is facilitated by the changes in orbital hybridization that favor different superexchange pathways. This can produce alternative magnetic structures when B″ is d¹⁰ or d⁰. Furthermore, the competition generated by introducing mixtures of d¹⁰ and d⁰ cations can drive the material into the realms of exotic quantum magnetism. Here, Te⁶⁺ d¹⁰ was substituted by W⁶⁺ d⁰ in the hexagonal perovskite Ba₂CuTeO₆, which possesses a spin ladder geometry of Cu²⁺ ca
