Anisotropic magnetoelastic coupling in single-crystalline CeFeAsO as seen via high-resolution x-ray diffraction
H. -F. Li, J. -Q. Yan, J. W. Kim +3
Single-crystal synchrotron x-ray diffraction studies of CeFeAsO reveal strong anisotropy in the charge correlation lengths along or perpendicular to the in-plane antiferromagnetic…
Magnetic and lattice coupling in single-crystal SrFeAs: A neutron scattering study
Haifeng Li, Wei Tian, Jerel L. Zarestky +7
A detailed elastic neutron scattering study of the structural and magnetic phase transitions in single-crystal SrFeAs reveals that the orthorhombic (O)-tetragonal (T) and t…
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…
The magnetic form factor of iron in SrFe2As2
Y. Lee, David Vaknin, Haifeng Li +7
The iron magnetic form factor in SrFe2As2 has been determined by neutron diffraction and by density functional theory (DFT). As noted previously, the magnitude of the calculated mo…
Paramagnetic Spin Correlations in CaFe2As2 Single Crystals
S. O. Diallo, D. K. Pratt, R. M. Fernandes +13
Magnetic correlations in the paramagnetic phase of CaFe2As2 (T_N=172 K) have been examined by means of inelastic neutron scattering from 180 K (~ 1.05 T_N) up to 300 K (~1.8 T_N).…
Magnetic field induced orientation of superconducting MgB crystallites determined by X-ray diffraction
J. Li, D. Vaknin, S. L. Bud'ko +5
X-ray diffraction studies of fine polycrystalline samples of MgB in the superconducting state reveal that crystals orient with their \emph{c}-axis in a plane normal to the dire…
