We present an in-depth analysis of MnRuAs, a compound crystallizing in the P$\bar{6}$2m symmetry with a distorted kagome lattice, revealing its distinctive structural, magnetic, and electronic properties through state-of-the-art ab initio calculations. By incorporating strong correlation effects using the DFT+U approach, we demonstrate the stabilization of MnRuAs, transforming its inherent dynamical instability into a robust ferromagnetic state with significant coupling along the $c$ axis. The calculated magnon dispersion reveals a parabolic profile with a minimum at the $Γ$ point, indicative of ferromagnetic behavior. Furthermore, MnRuAs exhibits intriguing electronic properties, including quasi-one-dimensional Fermi surface and the formation of nodal sphere. Our study also delves into the electronic surface states and constant energy contours, offering valuable insights into the complex physics of this material.
Anomalous Hall effect in distorted kagome magnets (Nd, Sm)Mn$_6$Sn$_6$
本文报道了NdMn $_6$ Sn $_6$和SmMn $_6$ Sn $_6$单晶的磁性和电学性质。与含重稀土的RMn $_6$ Sn $_6$化合物中的原始kagome晶格相比，它们结晶成具有扭曲的Mn基kagome晶格的结构。它们是高温铁磁体，其R磁矩与Mn磁矩平行。我们观察到一个大的固有异常霍尔效应（AHE），是在很宽的温度范围内的亚铁磁，重R兄弟姐妹相媲美。我们的结论是，它们的本征AHE源于锰基kagome晶格，就像在重RMn $_6$ Sn $_6$。
