AI 中文摘要
本研究提出一种展示共线反常磁体（altermagnets）特有的独特自旋分裂的新方法：在采样一般k点的布里渊区路径上绘制能带结构，以呈现与布里渊区平均对应的代表性图像，这与传统在最高对称点和连线上绘制能带结构的方法形成对比，传统方法在很多情况下根本无法显示任何反常磁自旋分裂。本研究将该新方法与传统方法绘制的共线反常磁体能带结构进行对比，报告了MnTe、CrSb、SmFeO3、ScCrO3、LaMnO3、TlCrO3、HoFeO3、InCrO3和DyFeO3的能带结构及对称性分析，结果清晰证明了该新方法在展示共线反常磁体自旋分裂方面的优势。
英文摘要
In this work we demonstrate a novel approach to exhibit the unique spin splitting that is typical of collinear altermagnets. This approach is to plot band structures on Brillouin zone paths that sample general k-points to show a representative picture that corresponds to Brillouin zone averages. This is in contrast to conventional band structure plotting which plots band structures on the highest-symmetry points and lines, and thus in many cases can fail to show any altermagnetic spin splitting at all. Our investigation compares the new approach with the band structures of collinear altermagnets using conventional band structure plotting. We report the band structure and symmetry analysis for MnTe, CrSb, SmFeO3, ScCrO3, LaMnO3, TlCrO3, HoFeO3, InCrO3 and DyFeO3. This result clearly demonstrates the advantage of this novel method for displaying the spin splitting of collinear altermagnets.
