Y. Zhang,Lexian Yang,Min Xu,Z. R. Ye,Feng Chen,C. He,Juan Jiang,Binping Xie,J. J. Ying,X. F. Wang,X. H. Chen,Jiangping Hu,Donglai Feng +12 more
TL;DR: In this paper, the low energy band structure and Fermi surface of the newly discovered superconductor, AxFe2Se2 (A=K,Cs), have been studied by angle-resolved photoemission spectroscopy.
Journal ArticleDOI
Different resistivity response to spin density wave and superconductivity at 20 K in $Ca_{1-x}Na_xFe_2As_2$
Gang Wu,H. F. Chen,Tao Wu,Xie Yijin,Y. J. Yan,Ronghua Liu,X. F. Wang,Jianjun Ying,X. H. Chen +8 more
TL;DR: In this article, the intrinsic transport and magnetic properties, and their anisotropy from high quality single crystal $CaFe_2As_2$ were investigated and it was shown that the resistivity response to spin-density-wave ordering is helpful to understand the role played by SDW ordering in Fe-based high-$T_c$ superconductors.
Journal ArticleDOI
Three-Dimensional Charge Density Wave and Surface-Dependent Vortex-Core States in a Kagome Superconductor CsV 3 Sb 5
Zuowei Liang,Xingyuan Hou,Fan Zhang,Fan Zhang,Wanru Ma,Ping Wu,Zongyuan Zhang,Fanghang Yu,J. J. Ying,Kun Jiang,Lei Shan,Zhenyu Wang,X. H. Chen,X. H. Chen +13 more
TL;DR: In this article, tunneling microscopy of a kagome superconductor was used to confirm a number of previously hinted at electronic states, including the existence of a triangular lattice of atoms.
Journal ArticleDOI
Sudden reversal in the pressure dependence ofTc in the iron-based superconductor KFe2As2
Fazel Tafti,A. Juneau-Fecteau,M-È. Delage,S. René de Cotret,J-Ph. Reid,J-Ph. Reid,Aifeng Wang,X-G. Luo,X. H. Chen,Nicolas Doiron-Leyraud,Louis Taillefer,Louis Taillefer +11 more
TL;DR: In this article, transport measurements suggest that pressure drives the superconducting state in KFe2As2 from d-wave to s-wave, and different probes have found different pairing states in different iron-based high-temperature superconductors.
Journal ArticleDOI
Coexistence of superconductivity and antiferromagnetism in single crystals $A_{0.8}Fe_{2-y}Se_2$ (A= K, Rb, Cs, Tl/K and Tl/Rb): evidence from magnetization and resistivity
Ronghua Liu,X. G. Luo,M. Zhang,Aifeng Wang,Jianjun Ying,X. F. Wang,Yajun Yan,Ziji Xiang,P. Cheng,G. J. Ye,Zhenyu Li,X. H. Chen +11 more
TL;DR: In this paper, the authors measured the resistivity and magnetic susceptibility in the temperature range from 5 K to 600 K for the single crystals, and observed a sharp superconducting transition in low temperature resistivities and susceptibility, and susceptibility shows 100% Meissner volume fraction for all crystals.
