Topological Hall Effect in a Topological Insulator Interfaced with a Magnetic Insulator
Peng Li, Jinjun Ding, Steven S. -L. Zhang +13
A topological insulator (TI) interfaced with a magnetic insulator (MI) may host an anomalous Hall effect (AHE), a quantum AHE, and a topological Hall effect (THE). Recent studies,…
The influence of alloying on the stacking fault energy of gold from density functional theory calculations
Anuj Goyal, Yanzhong Li, Aleksandr Chernatynskiy +4
The generalized stacking fault (SFE) energy curves of pure gold (Au) and its binary alloys with transition metals are determined from density functional theory (DFT). Alloy element…
Comprehensive Anisotropic Linear Optical Properties of Weyl Semimetals, TaAs and NbAs
Rui Zu, Mingqiang Gu, Lujin Min +5
TaAs and NbAs are two of the earliest identified Weyl semimetals that possess many intriguing optical properties, such as chirality-dependent optical excitations and giant second h…
Route to in situ synthesis of epitaxial Pr2Ir2O7 thin films guided by thermodynamic calculations
Lu Guo, Shun-Li Shang, Neil Campbell +4
In situ growth of pyrochlore iridate thin films has been a long-standing challenge due to the low reactivity of Ir at low temperatures and the vaporization of volatile gas species…
Scanning Transmission Electron Tomography and Electron Energy Loss Spectroscopy of Silicon Metalattices
Shih-Ying Yu, Hiu Yan Cheng, Jennifer L. Dysart +6
Transmission electron microscopy, scanning transmission electron tomography, and electron energy loss spectroscopy were used to characterize three-dimensional artificial Si nanostr…
Recent advancements in the study of intrinsic magnetic topological insulators and magnetic Weyl semimetals
Wei Ning, Zhiqiang Mao
The studies of topological insulators and topological semimetals have been at frontiers of condensed matter physics and material science. Both classes of materials are characterize…
