Structure, Spin Correlations, and Magnetism of the S=1/2 Square-Lattice Antiferromagnet Sr2CuTe1-xWxO6 (0 ≤ x ≤ 1)
Henrik Moodysson Rønnow, Ellen Fogh, Peter Babkevich, Sami Juhani Vasala
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. Isostru ...
Washington2023Exchange Interactions Mediated by Nonmagnetic Cations in Double Perovskites
Henrik Moodysson Rønnow, Oleg Yazyev, Peter Babkevich, Vamshi Mohan Katukuri, Sami Juhani Vasala
Establishing the physical mechanism governing exchange interactions is fundamental for exploring exotic phases such as quantum spin liquids in real materials. In this Letter, we address exchange interactions in Sr2CuTexW1-xO6, a series of double perovskite ...
AMER PHYSICAL SOC2020Spin wave excitations in the tetragonal double perovskite Sr2CuWO6
Sr2CuWO6 is a double perovskite proposed to be at the border between two- and three-dimensional magnetism, with a square lattice of S = 1/2 Cu2+ ions. We have used inelastic neutron scattering to investigate the spin wave excitations of the system, to find ...
