- ... The isostructural double perovskites Ba₂CuTeO₆ and Ba₂CuWO₆ are shown by theory and experiment to be frustrated square-lattice antiferromagnets with opposing dominant magnetic interactions. This is driven by differences in orbital hybridisation of Te⁶⁺ and W⁶⁺. A spin-liquid-like ground state is predicted for Ba₂Cu(Te₁₋ₓWₓ)O₆ solid solution similar to recent observations in Sr₂Cu(Te₁₋ₓWₓ)O₆. ...
