Effect of Li-deficiency impurities on the electron-overdoped LiFeAs superconductor
Meng Wang, Miaoyin Wang, Hu Miao +11
We use transport, inelastic neutron scattering, and angle resolved photoemission experiments to demonstrate that the stoichiometric LiFeAs is an intrinsically electron-overdoped su…
Magnetic order tuned by Cu substitution in Fe1.1-zCuzTe
Jinsheng Wen, Zhijun Xu, Guangyong Xu +7
We study the effects of Cu substitution in Fe1.1Te, the non-superconducting parent compound of the iron-based superconductor, Fe1+yTe1-xSex, utilizing neutron scattering techniques…
Spin reorientation in TlFe1.6Se2 with complete vacancy ordering
Andrew F. May, Michael A. McGuire, Huibo Cao +5
The relationship between vacancy ordering and magnetism in TlFe1.6Se2 has been investigated via single crystal neutron diffraction, nuclear forward scattering, and transmission ele…
Magnetic excitations in underdoped Ba(Fe1-xCox)2As2 with x=0.047
G. S. Tucker, R. M. Fernandes, H. -F. Li +8
The magnetic excitations in the paramagnetic-tetragonal phase of underdoped Ba(Fe0.953Co0.047)2As2, as measured by inelastic neutron scattering, can be well described by a phenomen…
Evolution of the nuclear and magnetic structures of TlFe1.6Se2 with temperature
Huibo Cao, Claudia Cantoni, Andrew F. May +6
The evolution of the nuclear and magnetic structures of TlFeSe was determined in the temperature range of 5-450\,K using single crystal neutron diffraction. The Fe laye…
