论文摘要
最近的理论研究表明，Kitaev物理学和诸如神秘旋转状态的效果不仅可以在RUCL3和Iridates中，而且可以预期在常规的$ 3D $过渡金属化合物中。使用DC和AC磁力测定法，热力学和$^{23} $ NA核磁共振测量（NMR）我们研究了这种候选材料Na3Co2SBO6。提出了Na3Co2SBO6的全相图，并在广泛的磁场和温度下显示。结果表明，在外部磁场下，抗铁磁结构的转化，饱和阶段的逐渐发展以及相图的某些部位的差异行为的证据
Recent theoretical studies have suggested that Kitaev physics and such effects as formation of a mysterious spin-liquid state can be expected not only in RuCl3 and iridates, but also in conventional $3d$ transition metal compounds. Using DC and AC magnetometry, thermodynamic and $^{23}$Na nuclear magnetic resonance measurements (NMR) we studied such a candidate material Na3Co2SbO6. A full phase diagram of Na3Co2SbO6 in a wide range of magnetic fields and temperatures is presented. The results demonstrate transformation of the antiferromagnetic structure under the external magnetic field, gradual development of the saturation phase, as well as evidence of gapped behavior in certain parts of the phase diagram
