| 英文摘要 | In this paper, we study the spin excitation properties of the frustrated triangular-lattice antiferromagnet Yb(BaBO3)(3) with nuclear magnetic resonance. From the spectral analysis, neither magnetic ordering nor spin freezing is observed with temperature down to T = 0.26 K, far below its Curie-Weiss temperature vertical bar theta(w)vertical bar similar to 2.3 K. From the nuclear relaxation measurement, precise temperature-independent spin-lattice relaxation rates are observed at low temperatures under a weak magnetic field, indicating the gapless spin excitations. Further increasing the field intensity, we observe a spin excitation gap with the gap size proportional to the field intensity. These phenomena suggest a very unusual strongly correlated quantum disordered phase, and the implications for the quantum spin liquid state are further discussed. |
