Vortex dynamics as a function of field orientation in BaFe1.9Ni0.1As2
S. Salem-Sugui, L. Ghivelder, A. D. Alvarenga +3
Vortex dynamics in a multiband anisotropic superconducting such as the Fe based superconductors, is interesting and potentially important for applications. In this study we examine…
Paramagnetic spin excitations in insulating RbFeSe
Miaoyin Wang, Xingye Lu, R. A. Ewings +6
We use neutron scattering to study temperature dependent spin excitations in insulating antiferromagnetic (AF) RbFeSe. In the low-temperature AF state, spin wav…
Flux-creep in the second magnetization peak of BaFe{1.9}Ni{0.1}As2 superconductor
S. Salem-Sugui, L. Ghivelder, A. D. Alvarenga +3
Flux-creep data was obtained for fields along the second magnetization peak observed in M(H) curves of BaFe{1.9}Ni{0.1}As2 for H||c-axis. H||ab-planes and H forming a 45 degrees an…
Electron doping evolution of the anisotropic spin excitations in BaFe2-xNixAs2
Huiqian Luo, Zahra Yamani, Yanchao Chen +7
We use inelastic neutron scattering to systematically investigate the Ni-doping evolution of the low-energy spin excitations in BaFe2-xNixAs2 spanning from underdoped antiferromagn…
