Motivated by the recent progress on the spin-orbit-coupled triangular lattice spin liquid candidate YbMgGaO4, we carry out a systematic projective symmetry group analysis and mean-field study of candidate U(1) spin liquid ground states. Due to the spin-orbital entanglement of the Yb moments, the space group symmetry operation transforms both the position and the orientation of the local moments, and hence brings different features for the projective realization of the lattice symmetries from the cases with spin-only moments. Among the eight U(1) spin liquids that we find with the fermionic parton construction, only one spin liquid state, that was proposed and analyzed in Yao Shen, et. al., Nature 540, 559-562 (2016) and labeled as U1A00 in the present work, stands out and gives a large spinon Fermi surface and provides a consistent explanation for the spectroscopic results in YbMgGaO4. Further connection of this spinon Fermi surface U(1) spin liquid with YbMgGaO4 and the future directions are discussed. Finally, our results may apply to other spinorbit-coupled triangular lattice spin liquid candidates, and more broadly, our general approach can be well extended to spin-orbit-coupled spin liquid candidate materials.

“…From the crystal electric field analysis in Ref. 5, the ground state doublet of the Ce 3+ ion in CeCd 3 P 3 does belong to the same kind of Kramers' doublet as the Yb 3+ ion in YbMgGaO 4 . Because the system remains paramagnetic down to 0.48K, the authors in Ref.…”

“…In the RZn 3 P 3 , RCd 3 P 3 , RZn 3 As 3 and RCd 3 As 3 materials' family, the rare earth ions, R 3+ , form triangular layers [5][6][7][8] . Since the interlayer separation is much larger than the intralayer lattice constant, one can safely neglect the interlayer coupling.…”

“…The thermodynamic and NMR measurements found that the system remains disordered down to 60mK 3 . More recently, another rareearth triangular antiferromagnet CeCd 3 P 3 was studied experimentally 5 . Although this material remains paramagnetic down to 0.48K and this temperature is probably not very low by the 4f electrons' standard, as we show in Table I, CeCd 3 P 3 and the rare-earth oxy-carbonates R 2 O 2 CO 3 represent new family of rare-earth triangular antiferromagnets that need further investigation [5][6][7][8] .…”

Anisotropic spin model of strong spin-orbit-coupled triangular antiferromagnets

Motivated by the recent experimental progress on the strong spin-orbit-coupled rare earth triangular antiferromagnet, we analyze the highly anisotropic spin model that describes the interaction between the spin-orbit-entangled Kramers' doublet local moments on the triangular lattice. We apply the Luttinger-Tisza method, the classical Monte Carlo simulation, and the self-consistent spin wave theory to analyze the anisotropic spin Hamiltonian. The classical phase diagram includes the 120• state and two distinct stripe ordered phases. The frustration is very strong and significantly suppresses the ordering temperature in the regimes close to the phase boundary between two ordered phases. Going beyond the semiclassical analysis, we include the quantum fluctuations of the spin moments within a self-consistent Dyson-Maleev spin-wave treatment. We find that the strong quantum fluctuations melt the magnetic order in the frustrated regions. We explore the magnetic excitations in the three different ordered phases as well as in strong magnetic fields. Our results provide a guidance for the future theoretical study of the generic model and are broadly relevant for strong spin-orbit-coupled triangular antiferromagnets such as YbMgGaO4, RCd3P3, RZn3P3, RCd3As3, RZn3As3, and R2O2CO3.
