Abstract: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 NaYbS2 being a prominent example.Here we present the solid-solution series NaYb1−xLuxS2 with well-defined single crystals over the entire substitution range 0 ≤ x ≤ 1. Chemical and structural analysis indicate a statistically homogeneous replacement of Yb 3+ by Lu 3+ ions. We magnetically characterize the relatively small single crystals using electron spi… Show more
