Diluting a triangular-lattice spin liquid: Synthesis and characterization of NaYb${}_{1-x}$Lu${}_x$S${}_2$ single crystals

Ellen Häußler, Jörg Sichelschmidt, Michael Baenitz +3

Yb-based magnets, with a perfect triangular lattice of pseudospin-$1/2$ Yb${}^{3+}$ ions, have emerged as candidates for realizing a quantum spin-liquid state, with NaYbS${}_2$ being a…
