Impact of localized magnetism on Berry curvature and the intrinsic anomalous Hall effect in CeRuSi
Takehiro Kobayashi, Shunsuke Hirai, Ibuki Terada +1
The intrinsic anomalous Hall effect (AHE), originating from Berry curvature, has been extensively studied in -electron systems, including Ce-based compounds. However, how the ma…
Optical anisotropy and electronic states in the pleochroic material CaReOCl
Takumi Tsukihara, Ibuki Terada, Michi-To Suzuki
Pleochroism is a type of optical anisotropy in which the apparent color of a material varies depending on the polarization and propagation direction of incident light. The oxychlor…
Nodal-line-enhanced quantum geometric effects: anomalous and nonlinear Hall effects in the parity-mixed antiferromagnet NbMnP
Ibuki Terada, Vu Thi Ngoc Huyen, Yuki Yanagi +1
The anomalous Hall effect has been understood in terms of the geometric nature of Bloch bands and impurity scattering, and has been observed in a wide variety of magnetic materials…
Wannier based analysis of the direct-indirect bandgap transition by stacking MoS layers
Shunsuke Hirai, Ibuki Terada, Michi-To Suzuki
Molybdenum disulfide (MoS), a layered van der Waals material, has attracted considerable attention as a promising alternative to graphene for applications in field-effect trans…
