Journal ArticleDOI
Strong interplay between stripe spin fluctuations, nematicity and superconductivity in FeSe
Qisi Wang,Yao Shen,Bingying Pan,Yiqing Hao,Mingwei Ma,Fang Zhou,P. Steffens,Karin Schmalzl,Thomas Forrest,Mahmoud Abdel-Hafiez,Xiao-Jia Chen,Dmitriy A. Chareev,Alexander N. Vasiliev,Alexander N. Vasiliev,Alexander N. Vasiliev,P. Bourges,Yvan Sidis,Huibo Cao,Jun Zhao +18 more
TL;DR: The results support recent theoretical proposals that both nematicity and superconductivity are driven by spin fluctuations.
Journal ArticleDOI
Magnetic ground state of FeSe.
Qisi Wang,Yao Shen,Bingying Pan,Xiaowen Zhang,K. Ikeuchi,Kazuki Iida,Andrew D. Christianson,Helen Walker,D. T. Adroja,Mahmoud Abdel-Hafiez,Xiao-Jia Chen,Dmitriy A. Chareev,Alexander N. Vasiliev,Jun Zhao +13 more
TL;DR: Inelastic neutron-scattering experiments that reveal both stripe and Néel spin fluctuations over a wide energy range at 110 K suggest that FeSe is a novel S=1 nematic quantum-disordered paramagnet interpolating between the NÉel and stripe magnetic instabilities.
Journal ArticleDOI
Strong Interplay between Stripe Spin Fluctuations, Nematicity and Superconductivity in FeSe
Qisi Wang,Yao Shen,Bingying Pan,Yiqing Hao,Mingwei Ma,Fang Zhou,P. Steffens,Karin Schmalzl,Thomas Forrest,Mahmoud Abdel-Hafiez,Dmitriy A. Chareev,Alexander N. Vasiliev,P. Bourges,Yvan Sidis,Huibo Cao,Jun Zhao +15 more
TL;DR: In this article, the authors used neutron scattering to study structurally the simplest iron-based superconductor FeSe, which displays a nematic (orthorhombic) phase transition at $T_s=90$ K, but does not order antiferromagnetically.
Journal ArticleDOI
Anomalous correlation effects and unique phase diagram of electron-doped FeSe revealed by photoemission spectroscopy.
C. H. P. Wen,Haichao Xu,Chen Chen,Z. C. Huang,Xia Lou,Y. J. Pu,Qi Song,Binping Xie,Mahmoud Abdel-Hafiez,Dmitriy A. Chareev,Alexander N. Vasiliev,Rui Peng,Donglai Feng +12 more
TL;DR: In this paper, an anomalous phase diagram of FeSe with electron doping was discovered, including a nematic phase, a superconducting dome, a correlation-driven insulating phase and a metallic phase.
Journal ArticleDOI
Temperature dependence of lower critical field Hc1(T) shows nodeless superconductivity in FeSe
Mahmoud Abdel-Hafiez,Jun-Yi Ge,Alexander N. Vasiliev,Alexander N. Vasiliev,Dmitriy A. Chareev,J. Van de Vondel,V. V. Moshchalkov,Alejandro Silhanek +7 more
TL;DR: In this paper, the temperature dependence of the lower critical field Hc1(T) of a high-quality FeSe single crystal under static magnetic fields H parallel to the c axis was investigated.
