First-principles study of spin orbit coupling contribution to anisotropic magnetic interaction
Di Wang, Xiangyan Bo, Feng Tang +1
Anisotropic magnetic exchange interactions lead to a surprisingly rich variety of the magnetic properties. Considering the spin orbit coupling (SOC) as perturbation, we extract the…
Discovery of a metallic oxide with ultralow thermal conductivity
Jianhong Dai, Zhehong Liu, Jialin Ji +10
A compound with metallic electrical conductivity usually has a considerable total thermal conductivity because both electrons and photons contribute to thermal transport. Here, we…
Magnetic interactions and possible structural distortion in kagome FeGe from first-principles study and symmetry analysis
Hanjing Zhou, Songsong Yan, Dongze Fan +2
Based on density functional theory and symmetry analysis, we present a comprehensive investigation of electronic structure, magnetic properties and possible structural distortion o…
Continuous Electrical Manipulation of Magnetic Anisotropy and Spin Flopping in van der Waals Ferromagnetic Devices
Ming Tang, Junwei Huang, Feng Qin +19
Controlling the magnetic anisotropy of ferromagnetic materials plays a key role in magnetic switching devices and spintronic applications. Examples of spin-orbit torque devices wit…
All hourglass bosonic excitations in the 1651 magnetic space groups and 528 magnetic layer groups
Dongze Fan, Xiangang Wan, Feng Tang
The band connectivity as imposed by the compatibility relations between the irreducible representations of little groups can give rise to the exotic hourglass-like shape composed o…
Observation of robust zero-energy state and enhanced superconducting gap in a tri-layer heterostructure of MnTe/Bi2Te3/Fe(Te, Se)
Shuyue Ding, Chen Chen, Zhipeng Cao +11
The interface between magnetic material and superconductors has long been predicted to host unconventional superconductivity, such as spin-triplet pairing and topological nontrivia…
