Observation of topological nodal-line semimetal in YbMnSb2 through optical spectroscopy
Ziyang Qiu, Congcong Le, Zhiyu Liao +5
The optical properties of YbMnSb2 have been measured in a broad frequency range from room temperature down to 7 K. With decreasing temperature, a flat region develops in the optica…

Infrared spectroscopic studies of the topological properties in CaMnSb2
Ziyang Qiu, Congcong Le, Yaomin Dai +6
We present temperature-dependent infrared spectroscopic studies of CaMnSb2, a proposed threedimensional topological material. The low plasma edge in the reflectivity spectrum and s…

Optical study of the antiferromagnetic ordered state in electron-overdoped Ca0.77Nd0.23FeAs2
Run Yang, Bing Xu, Yaomin Dai +4
In Ca1-xRExFeAs2 (RE= rare earth), an antiferromagnetic (AFM) phase as well as a structural transition has been reported, even in the electron-overdoped regime. Here we investigate…
