Frustrated Magnetism in Triangular Lattice TlYbS${}_2$ Crystals Grown via Molten Flux

Abstract

The triangular lattice compound TlYbS${}_2$ was prepared as large single crystals via a molten flux growth technique using sodium chloride. Anisotropic magnetic susceptibility measurements down to 0.4 K indicate a complete absence of long-range magnetic order. Despite this lack of long-range order, short-range antiferromagnetic interactions are evidenced through broad transitions, suggesting frustrated behavior. Variable magnetic field measurements reveal metamagnetic behavior at temperatures less than 2 K. Complex low temperature field-tunable magnetic behavior, in addition to no observable long-range order down to 0.4 K, suggest that TlYbS${}_2$ is a frustrated magnet and a possible quantum spin liquid candidate.
