c-axis pressure induced antiferromagnetic order in optimally P-doped BaFe2(As0.70P0.30)2 superconductor
Ding Hu, Weiyi Wang, Wenliang Zhang +14
Superconductivity in BaFe2(As1-xPx)2 iron pnictides emerges when its in-plane two-dimensional (2D) orthorhombic lattice distortion associated with nematic phase at Ts and three-dim…
Unusual suppression of a spin resonance mode with magnetic field in underdoped NaFeCoAs: Evidence for orbital-selective pairing
Yu Song, Guotai Tan, Chenglin Zhang +3
We use inelastic neutron scattering to study the fate of the two spin resonance modes in underdoped superconducting NaFeCoAs () under applied magnetic fields.…
Local orthorhombic lattice distortions in the paramagnetic tetragonal phase of superconducting NaFeNiAs
Weiyi Wang, Yu Song, Chongde Cao +9
Understanding the interplay between nematicity, magnetism and superconductivity is pivotal for elucidating the physics of iron-based superconductors. Here we use neutron scattering…
Dynamic spin-lattice coupling and nematic fluctuations in NaFeAs
Yu Li, 1 Zahra Yamani, 2 Yu Song +14
We use inelastic neutron scattering to study acoustic phonons and spin excitations in single crystals of NaFeAs, a parent compound of iron pnictide superconductors. NaFeAs exhibits…
Persistent low-energy phonon broadening near the charge order -vector in bilayer cuprate BiSrCaCuO
Yu He, Shan Wu, Yu Song +23
We report a persistent low-energy phonon broadening around r.l.u. along the Cu-O bond direction in the high- cuprate BiSrCaCuO (Bi-2212).…
Disentangling superconducting and magnetic orders in NaFe_1-xNi_xAs using muon spin rotation
Sky C. Cheung, Zurab Guguchia, Benjamin A. Frandsen +24
Muon spin rotation and relaxation studies have been performed on a "111" family of iron-based superconductors NaFe_1-xNi_xAs. Static magnetic order was characterized by obtaining t…
Spin-isotropic continuum of spin excitations in antiferromagnetically ordered FeTe
Yu Song, Xingye Lu, L. -P. Regnault +5
Unconventional superconductivity typically emerges in the presence of quasi-degenerate ground states, and the associated intense fluctuations are likely responsible for generating…
