论文摘要
几何挫败感，扩展跳跃，旋转轨道耦合和无序磁接地状态的结合使Naruo $ _ {2} $成为有吸引力的Heisenberg-Kitaev候选材料。从历史上看，Naruo $ _2 $也是一种具有挑战性的材料，即使以多晶形式也是如此。在这里，我们提出了合成的努力，以确定Na $ _ \ text {ru} $缺陷的倾向，以naruo $ _2 $形成，揭示了Naruo $ _ {2} $与无序的Na $ _2 $ _2 $ _2 $ ruo $ _3 $之间的完整实心解决方案。我们报告了沿Na $ _ {3+x} $ ru $ _ {3-x} $ o $ $ $ _6 $实心解决方案的合成合成的合成，并表征块状磁化和电子传输的变化，这是NA载荷的函数。我们的结果强调了在调查和解释该材料的物理属性时，在Naruo $ _ {2} $中进行化学计量控制的重要性。
The combination of geometric frustration, extended hopping, spin-orbit coupling, and a disordered magnetic ground state make NaRuO$_{2}$ an attractive Heisenberg-Kitaev candidate material. Historically, NaRuO$_2$ has been a challenging material to produce, even in polycrystalline form. Here we present synthetic efforts that identify a propensity for Na$_\text{Ru}$ defects to form in NaRuO$_2$, revealing a full solid-solution between NaRuO$_{2}$ and disordered Na$_2$RuO$_3$. We report the synthesis of alloys along the Na$_{3+x}$Ru$_{3-x}$O$_6$ solid solution and characterize changes in the bulk magnetization and electron transport as a function of Na-loading. Our results highlight the importance of stoichiometry control in NaRuO$_{2}$ when investigating and interpreting this material's physical properties.
