  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.
