Spin excitation anisotropy in optimal-isovalent-doped superconductor BaFe2(As0.7P0.3)2
Ding Hu, Wenliang Zhang, Yuan Wei +8
We use neutron polarization analysis to study spin excitation anisotropy in the optimal-isovalent-doped superconductor BaFe2(As0.7P0.3)2 (Tc = 30 K). Different from optimally hole…
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…
Local breaking of four-fold rotational symmetry by short-range magnetic order in heavily overdoped Ba(FeCu)As
Weiyi Wang, Yu Song, Ding Hu +6
We investigate Cu-doped Ba(FeCu)As with transport, magnetic susceptibility, and elastic neutron scattering measurements. In the heavily Cu-doped regime where lo…
Direct observation of magnon-phonon coupling in yttrium iron garnet
Haoran Man, Zhong Shi, Guangyong Xu +7
The magnetic insulator yttrium iron garnet (YIG) with a ferrimagnetic transition temperature of 560 K has been widely used in microwave and spintronic devices. Anomalous feat…
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…
