论文摘要
关于真实材料的拓扑运输已经了解了很多。我们研究了prrhc $ _2 $的磁电交易中磁性和拓扑之间的相互作用。当磁性量化轴的方向从易于轴转换为从易于的轴线，通过面部对角线将磁量化轴的方向更改为磁量化轴的方向时，四倍的退化率将其降低到两倍，然后是非分类的Weyl节点。这会导致围绕费米能量周围的正性和负性韦伊尔节点之间的手性失衡。我们观察到手性异常介导的反应的显着增强，例如平面霍尔电导率和纵向磁导率，这是由于将磁量化轴定向到人体 - 双基因时的导致手性不平衡的出现。上述不同磁量化轴的上述数量的角变化清楚地指出了韦伊尔半学中平面霍尔效应的典型特征。我们进一步研究了异常大厅电导率的曲线，这是费米能量的函数，以探索对称性以及手性失衡对浆果曲率的影响。
Much has been learned about the topological transport in real materials. We investigate the interplay between magnetism and topology in the magneto-transport of PrRhC$_2$. The four-fold degeneracy reduces to two-fold followed by non-degenerate Weyl nodes when the orientation of the magnetic quantization axis is changed from easy axis to body-diagonal through face-diagonal. This engenders chirality imbalance between positive and negative chirality Weyl nodes around the Fermi energy. We observe a significant enhancement in the chiral anomaly mediated response such as planar Hall conductivity and longitudinal magneto-conductivity, due to the emergence of chirality imbalance upon orienting the magnetic quantization axis to body-diagonal. The angular variations of the above quantities for different magnetic quantization axis clearly refer to the typical signature of planar Hall effect in Weyl semimetals. We further investigate the profiles of anomalous Hall conductivities as a function of Fermi energy to explore the effects of symmetries as well as chirality imbalance on Berry curvature.
