“…Gapless spin excitations consistent with U(1) QSL ground state with spinon fermion surface were observed [32]. However, specific heat measurements and theoretical calculations suggest that Yb(BaBO 3 ) 3 may realize a quantum dipole lattice, where the exchange interactions are negligible [31]. It is worth noting that an energy gap with a gap size proportional to the field intensity was observed both in the NMR and thermodynamic studies.…”

“…Yb-based triangular lattice single crystals of Yb(BaBO 3 ) 3 have been synthesized recently. It was identified as a disorderfree triangular lattice [30,31]. Nuclear magnetic resonance (NMR) study and thermodynamic study on Yb(BaBO 3 ) 3 have been performed to figure out its ground state and explore its suitability as a QSL candidate [31,32].…”

We report results of magnetization, specific heat, and muon spin relaxation (μSR) measurements on single crystals of disorder-free Yb 3+ triangular lattice Yb(BaBO 3 ) 3 . The magnetization experiments show anisotropic magnetic properties with Curie-Weiss temperatures θ ⊥ = −1.40 K (H ⊥ c) and θ = −1.16 K (H c) determined from low-temperature data. The absence of both long-range antiferromagnetic order and spin freezing is confirmed down to 0.27 K at zero field. A two-level Schottky anomaly due to the opening of the ground-state Kramers doublet is observed from the low-temperature specific heat measurements when the applied magnetic fields μ 0 H > 0.7 T. At zero field, the increase of both C mag /T and the muon spin relaxation rate λ below 1 K is due to the electronic spin excitations, which often exist in quantum magnets where dipole-dipole interactions create an anisotropy of magnetic properties. The spin excitation is also supported by the unusual maximum of the field dependence of λ due to the field-induced increase in the density of excitations. We argue that dipolar interaction is dominant and induces the spin dynamics in the quantum magnet Yb(BaBO 3 ) 3 .

“…, where H is the applied field and H 0 accounts for a dipolar field from neighbouring ions, or possibly impurity spins [37,38]. This additional contribution is necessary to explain the zero-field splitting, which is evident from a lowtemperature upturn in the zero-field data.…”

We synthesise homogeneous compositions of NaLuxYb1−xSe2, connecting non-magnetic NaLuSe2 to the triangular lattice spin liquid candidate NaYbSe2. Thermal and magnetic properties are studied as the system evolves from one with dilute magnetic defects to one of a dense magnetic lattice. The field and temperature dependent heat capacity show the carriers of entropy crossover from isolated magnetic ions to a correlated lattice borne from spin dimers. For the dilute system we estimate the single ion anisotropy (g ⊥ /g = 3.13) and also the dimer exchange couplings J (= 5.4 K) and J ⊥ (= 9.6 K), in order to draw comparison to the half-doped and full magnetic compounds.
