Magnetic interactions in the $S = 1/2$ square-lattice antiferromagnets Ba $_{2}$ CuTeO $_{6}$ and Ba $_{2}$ CuWO $_{6}$ : parent phases of a possible spin liquid

arXiv:1812.05619 · doi:10.1039/C8CC09479A

Abstract

The isostructural double perovskites Ba $_{2}$ CuTeO $_{6}$ and Ba $_{2}$ CuWO $_{6}$ 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 Te $^{6 +}$ and W $^{6 +}$ . A spin-liquid-like ground state is predicted for Ba $_{2}$ Cu(Te $_{1 - x}$ W $_{x}$ )O $_{6}$ solid solution similar to recent observations in Sr $_{2}$ Cu(Te $_{1 - x}$ W $_{x}$ )O $_{6}$ .
