Strong local moment antiferromagnetic spin fluctuations in V-doped LiFeAs
Zhuang Xu, Guangyang Dai, Yu Li +15
We use neutron scattering to study vanadium (hole)-doped LiFeVAs. In the undoped state, LiFeAs exhibits superconductivity at K and transverse incommensurate sp…
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…
Reciprocity between local moments and collective magnetic excitations in the phase diagram of BaFe(AsP)
Jonathan Pelliciari, Kenji Ishii, Yaobo Huang +12
Unconventional superconductivity arises at the border between the strong coupling regime with local magnetic moments and the weak coupling regime with itinerant electrons, and stem…
Spin fluctuation anisotropy as a probe of orbital-selective hole-electron quasiparticle excitations in detwinned Ba(Fe1-xCox)2As2
Long Tian, Panpan Liu, Zhuang Xu +7
We use inelastic neutron scattering to study spin excitation anisotropy in mechanically detwinned Ba(Fe1-xCox)2As2 with x = 0.048 and 0.054. Both samples exhibit a tetragonal-to-or…
Anisotropic magnetic excitations of a frustrated bilinear-biquadratic spin model -- Implications for spin waves of detwinned iron pnictides
Changle Liu, Xingye Lu, Pengcheng Dai +2
Elucidating the nature of spin excitations is important to understanding the mechanism of superconductivity in the iron pnictides. Motivated by recent inelastic neutron scattering…
Plaquette instability competing with bicollinear ground state in detwinned FeTe
David W. Tam, Hsin-Hua Lai, Jin Hu +10
We use inelastic neutron scattering to show that long-range spin waves arising from the static bicollinear antiferromagnetic (AF) order in FeTe, which have twofold rotational symme…
