Neutron scattering studies on spin fluctuations in SrRuO
K. Jenni, S. Kunkemöller, P. Steffens +5
The magnetic excitations in SrRuO are studied by polarized and unpolarized neutron scattering experiments as a function of temperature. At the scattering vector of the Ferm…
Effect of Fermi Surface Nesting on Resonant Spin Excitations in Ba1-xKxFe2As2
J. -P. Castellan, S. Rosenkranz, E. A. Goremychkin +13
We report inelastic neutron scattering measurements of the resonant spin excitations in Ba1-xKxFe2As2 over a broad range of electron band filling. The fall in the superconducting t…
Spin Waves and Magnetic Exchange Interactions in CaFe2As2
Jun Zhao, D. T. Adroja, Dao-Xin Yao +7
Antiferromagnetism is relevant to high temperature (high-Tc) superconductivity because copper oxide and iron arsenide high-Tc superconductors arise from electron- or hole-doping of…
Evidence of spin density wave in LaFeAsO, the parent material of the new Fe-based oxypnictide superconductors
Motoyuki Ishikado, Ryoichi Kajimoto, Shin-ichi Shamoto +11
The Fe-based Oxypnicide superconductors have generated a huge amount of interest; they are a high temperature superconductor, with a Tc of 55K, but do not have the two dimensional…
High energy spin excitations in BaFe2As2
R. A. Ewings, T. G. Perring, R. I. Bewley +5
We report neutron scattering measurements of cooperative spin excitations in antiferromagnetically ordered BaFe2As2, the parent phase of an iron pnictide superconductor. The data e…
Resonant Spin Excitation in the High Temperature Superconductor Ba0.6K0.4Fe2As2
A. D. Christianson, E. A. Goremychkin, R. Osborn +9
The recent observations of superconductivity at temperatures up to 55K in compounds containing layers of iron arsenide have revealed a new class of high temperature superconductors…
