Dispersive Magnetic and Electronic Excitations in Iridate Perovskites Probed with Oxygen -Edge Resonant Inelastic X-ray Scattering
Xingye Lu, Paul Olalde-Velasco, Yaobo Huang +11
Resonant inelastic X-ray scattering (RIXS) experiments performed at the oxygen- edge on the iridate perovskites {\SIOS} and {\SION} reveal a sequence of well-defined dispersive…
Temperature and polarization dependence of low-energy magnetic fluctuations in nearly-optimal-doped NaFeCoAs
Yu Song, Weiyi Wang, Chenglin Zhang +8
We use unpolarized and polarized neutron scattering to study the temperature and polarization dependence of low-energy magnetic fluctuations in nearly-optimal-doped NaFe…
Two-dimensional Massless Dirac Fermions in Antiferromagnetic AFe2As2 (A = Ba, Sr)
Zhi-Guo Chen, Luyang Wang, Yu Song +7
We report infrared studies of AFeAs (A = Ba, Sr), two representative parent compounds of iron-arsenide superconductors, at magnetic fields (B) up to 17.5 T. Optical tra…
Spin excitation anisotropy in the paramagnetic tetragonal phase of BaFe2 As2
Yu Li, Weiyi Wang, Yu Song +4
We use neutron polarization analysis to study temperature dependence of the spin excitation anisotropy in BaFeAs, which has a tetragonal-to-orthorhombic structural distorti…
Local and collective magnetism of EuFeAs
Pelliciari Jonathan, Ishii Kenji, Dantz Marcus +9
We present an experimental study of the local and collective magnetism of , that is isostructural with the high temperature superconductor parent compound $\ma…
Uniaxial pressure effect on the magnetic ordered moment and transition temperatures in BaFeAs (Co, Ni)
David W. Tam, Yu Song, Haoran Man +22
We use neutron diffraction and muon spin relaxation to study the effect of in-plane uniaxial pressure on the antiferromagnetic (AF) orthorhombic phase in BaFeAs and its Co-…
