DyOCl: a rare-earth based two-dimensional van der Waals material with strong magnetic anisotropy
Congkuan Tian, Feihao Pan, Dehua Ye +17
Comparing with the widely known transitional metal based van der Waals (vdW) materials, rare-earth based ones are rarely explored in the research of intrinsic two-dimensional (2D)…
Evidence for anisotropic spin-triplet Andreev reflection at the 2D van der Waals ferromagnet/superconductor interface
Ranran Cai, Yunyan Yao, Peng Lv +11
Fundamental symmetry breaking and relativistic spin-orbit coupling give rise to fascinating phenomena in quantum materials. Of particular interest are the interfaces between ferrom…
Topological charge-entropy scaling in kagome Chern magnet TbMnSn
Xitong Xu, Jia-Xin Yin, Wenlong Ma +8
In ordinary materials, electrons conduct both electricity and heat, where their charge-entropy relations observe the Mott formula and the Wiedemann-Franz law. In topological quantu…
Room-temperature quantum spin Hall edge state in a higher-order topological insulator BiBr
Nana Shumiya, Md Shafayat Hossain, Jia-Xin Yin +24
Room-temperature realization of macroscopic quantum phenomena is one of the major pursuits in fundamental physics. The quantum spin Hall state, a topological quantum phenomenon tha…
Helicoid-arc van Hove singularities in topological chiral crystals
Daniel S. Sanchez, Tyler A. Cochran, Ilya Belopolski +14
Van Hove singularity are electronic instabilities that lead to many fascinating interactions, such as superconductivity and charge-density waves. And despite much interest, the nex…
Observation of orbital order in the Van der Waals material 1T-TiSe2
Yingying Peng, Xuefei Guo, Qian Xiao +11
Besides magnetic and charge order, regular arrangements of orbital occupation constitute a fundamental order parameter of condensed matter physics. Even though orbital order is dif…
