Query: Rare-earth triangular lattice spin liquid: a single-crystal study of
  YbMgGaO$_{4}$   YbMgGaO$_{4}$, a structurally perfect two-dimensional triangular lattice with
odd number of electrons per unit cell and spin-orbit entangled effective
spin-1/2 local moments of Yb$^{3+}$ ions, is likely to experimentally realize
the quantum spin liquid ground state. We report the first experimental
characterization of single crystal YbMgGaO$_{4}$ samples. Due to the spin-orbit
entanglement, the interaction between the neighboring Yb$^{3+}$ moments depends
on the bond orientations and is highly anisotropic in the spin space. We carry
out the thermodynamic and the electron spin resonance measurements to confirm
the anisotropic nature of the spin interaction as well as to quantitatively
determine the couplings. Our result is a first step towards the theoretical
understanding of the possible quantum spin liquid ground state in this system
and sheds new lights on the search of quantum spin liquids in strong spin-orbit
coupled insulators.
