AbstractNaYbO2 has been reported as a possible host for the quantum spin-liquid state. Here, the composition-dependent polycrystalline Na1-xYbO2 (x = 0, 0.03, and 0.07) has been investigated by combining high-field magnetizations and inelastic neutron scattering techniques. For the x = 0 sample, no signature of a magnetic order is observed down to 0.3 K. Inelastic neutron scattering measurement suggests a continuous low-energy excitation spectrum centered at momentum transfer (Q) similar to 1.25 angstrom(-1) and extending up to energy transfer (E) similar to 2.0 meV. In contrast, x = 0.03 and 0.07 samples exhibit magnetic transitions at 1.1 and 2.3 K, respectively. High-field magnetization measurements indicate similar behaviors for x = 0 and 0.03 samples including plateaulike features at the 1/3 saturated magnetization, which implies that the spin disorder in the x = 0 sample might be suppressed preceding the emergence of the up-up-down phase. This composition- and field-dependent study allows us to construct complete phase diagrams indicating that NaYbO2 is a promising candidate for the quantum spin-liquid state in close proximity to the antiferromagnetic instability tuned by the application of magnetic fields as well as controlling the concentration of Na+ ion vacancies.
