AI 中文摘要
我们报告了插层在范德华材料NbS₂层间的磁性过渡金属离子三角晶格堆叠序列的深远影响。通过单晶X射线和中子衍射、输运和磁化测量，我们发现V₁/₃NbS₂有两种不同的多型体，其磁化易轴和反常霍尔响应不同。非弹性中子散射数据的自洽分析为延伸至1nm的振荡RKKY相互作用提供了证据，该相互作用稳定了两种多型体中的准共线A型交替磁序，尽管易轴垂直。块状多型体晶体的详细堆叠序列极大地影响其宏观反常霍尔响应和磁性，这为设计层状三维固体的块状性质提供了新途径。
英文摘要
We report profound impacts of the stacking sequence of triangular lattices of magnetic transition metal ions intercalated between the layers of the van der Waals material NbS$_2$. Using single crystal x-ray and neutron diffraction, and transport and magnetization measurements, we show there are two distinct polytypes of $\rm V_{1/3}NbS_2$ with disparate easy axes of magnetization and different anomalous Hall responses. Self-consistent analysis of inelastic neutron scattering data provides evidence for oscillatory RKKY interactions that extend to 1 nm and stabilize quasi-collinear A-type altermagnetic orders in both polytypes though with perpendicular easy axes. The detailed stacking sequence of a bulk polytype crystal dramatically impact its macroscopic anomalous Hall response and magnetism, which suggests a new path to engineer the bulk properties of a layered three dimensional solid.
