Crossover from spin-waves to diffusive spin excitations in underdoped Ba(FeCo)As
G. S. Tucker, R. M. Fernandes, D. K. Pratt +12
Using inelastic neutron scattering, we show that the onset of superconductivity in underdoped Ba(FeCo)As coincides with a crossover from well-defined spin…
Doping dependence of the spin excitations in Fe-based superconductors Fe1+yTe1-xSex
A. D. Christianson, M. D. Lumsden, K. Marty +10
The Fe1+yTe1-xSex series of materials is one of the prototype families of Fe-based superconductors. To provide further insight into these materials we present systematic inelastic…
Competition between stripe and checkerboard magnetic instabilities in Mn-doped BaFe2As2
G. S. Tucker, D. K. Pratt, M. G. Kim +12
Inelastic neutron scattering measurements on Ba(Fe0.925Mn0.075)2As2 manifest spin fluctuations at two different wavevectors in the Fe square lattice, (1/2,0) and (1/2,1/2), corresp…
Effects of transition metal substitutions on the incommensurability and spin fluctuations in BaFe2As2 by elastic and inelastic neutron scattering
M. G. Kim, J. Lamsal, T. W. Heitmann +17
The spin fluctuation spectra from nonsuperconducting Cu-substituted, and superconducting Co-substituted, BaFe2As2 are compared quantitatively by inelastic neutron scattering measur…
