RKKY coupled local moment magnetism in NaFeCuAs
Yizhou Xin, Ingrid Stolt, Yu Song +2
A central question in a large class of strongly correlated electron systems, including heavy fermion compounds and iron pnictides, is the identification of different phases and the…
High-energy magnetic excitations from heavy quasiparticles in CeCuSi
Yu Song, Weiyi Wang, Chongde Cao +8
Magnetic fluctuations is the leading candidate for pairing in cuprate, iron-based and heavy fermion superconductors. This view is challenged by the recent discovery of nodeless sup…
Structural and Magnetic Transitions in the Planar Antiferromagnet BaIrO
Xiang Chen, Yu He, Shan Wu +7
We report the structural and magnetic ground state properties of the monoclinic compound barium iridium oxide BaIrO using a combination of resonant x-ray scattering,…
Spin dynamics in NaFeAs and NaFeCuAs probed by resonant inelastic X-ray scattering
Yu Song, Weiyi Wang, Eugenio Paris +11
The parent compounds of iron-based superconductors are magnetically-ordered bad metals, with superconductivity appearing near a putative magnetic quantum critical point. The presen…
Strain-induced spin-nematic state and nematic susceptibility arising from Fe clusters in KFeAgTe
Yu Song, Dongsheng Yuan, Xingye Lu +3
Spin nematics break spin-rotational symmetry while maintaining time-reversal symmetry, analogous to liquid crystal nematics that break spatial rotational symmetry while maintaining…
Stripe Antiferromagnetism and Disorder in the Mott Insulator NaFeCuAs ()
Yizhou Xin, Ingrid Stolt, Yu Song +2
Neutron scattering measurements have demonstrated that the heavily Cu-doped NaFeCuAs compound behaves like a Mott insulator exhibiting both real space Fe-Cu stripes,…
