Structure, Spin Correlations, and Magnetism of the S = 1/2 Square-Lattice Antiferromagnet Sr₂CuTe_1-xW_xO₆ (0 ≤ x ≤ 1).

ABSTRACT: Quantum spin liquids are highly entangled magnetic states with exotic properties. The S = 1/2 square-lattice Heisenberg model is one of the foundational models in frustrated magnetism with a predicted, but never observed, quantum spin liquid state. Isostructural double perovskites Sr₂CuTeO₆ and Sr₂CuWO₆ are physical realizations of this model but have distinctly different types of magnetic order and interactions due to a d¹⁰/d⁰ effect. Long-range magnetic order is suppressed in the solid solution Sr₂CuTe_1-xW_xO₆ in a wide region of x = 0.05-0.6, where the ground state has been proposed to be a disorder-induced spin liquid. Here, we present a comprehensive
