Gapped commensurate antiferromagnetic response in a strongly underdoped model cuprate superconductor
Zachary W. Anderson, Yang Tang, Vikram Nagarajan +13
It is a distinct possibility that spin fluctuations are the pairing interactions in a wide range of unconventional superconductors. In the case of the high-transition-temperature (…
Spin dynamics in itinerant antiferromagnet SrCrAs
Zhenhua Ning, Pinaki Das, Y. Lee +6
SrCrAs is an itinerant antiferromagnet in the same structural family as the SrFeAs high-temperature superconductors. We report our calculations of exchange-coupling…
Neutron Scattering Measurements of Spatially Anisotropic Magnetic Exchange Interactions in Semiconducting K0.85Fe1.54Se2 (TN=280 K)
Jun Zhao, Yao Shen, R. J. Birgeneau +7
We use neutron scattering to study the spin excitations associated with the stripe antiferromagnetic (AFM) order in semiconducting KFeSe (= K). We s…
Commensurate antiferromagnetic excitations as a signature of the pseudogap in the tetragonal high-Tc cuprate HgBaCuO
M. K. Chan, C. J. Dorow, L. Mangin-Thro +12
Antiferromagnetic correlations have been argued to be the cause of the d-wave superconductivity and the pseudogap phenomena exhibited by the cuprates. Although the antiferromagneti…
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…
Anisotropic and quasipropagating spin excitations in superconducting Ba(Fe0.926Co0.074)2As2
H. -F. Li, C. Broholm, D. Vaknin +12
Inelastic neutron scattering from superconducting (SC) Ba(FeCo)As reveals anisotropic and quasi-two-dimensional (2D) magnetic excitations close to \text…
