反铁磁半金属EuCd2Pn2(Pn=As,Sb)中磁交换诱导的外尔态OA北大核心CSCD
Magnetic exchange induced Weyl states in the antiferromagnetic semimetals EuCd2Pn2 (Pn = As, Sb)
由于丰富的拓扑量子效应及巨大的潜在应用价值,拓扑材料逐渐成为凝聚态物理前沿的研究材料体系.其中,作为与石墨烯具有相似电子结构的材料,三维拓扑半金属吸引了越来越多的研究兴趣.目前已知的拓扑半金属大多为非磁性的,而磁性拓扑半金属数量有限,与非磁性拓扑半金属相比较,研究开展的还比较少.磁性与拓扑之间的相互作用能够导致非常规的物理性质,如反常霍尔效应甚至量子反常霍尔效应等.此外,在一些具有特殊磁结构的拓扑半金属中,施加外磁场能够调制其自旋结构,从而影响其…查看全部>>
Three-dimensional (3D) topological semimetals (TSMs) have arrested special at-tentions as 3D analogues to graphene. The TSMs, for example, the Dirac and Weyl semimetals, show an array of intriguing physical properties arising from the electronic band structure topol-ogy, which have therefore been under immense investigations. Most of the known TSMs are nonmagnetic, whereas the magnetic TSMs are very few and remain less investigated. The in-terplay between ma…查看全部>>
