Determining the Short-Range Spin Correlations in Cuprate Chain Materials with Resonant Inelastic X-ray Scattering
Claude Monney, Valentina Bisogni, Ke Jin Zhou +13
We report a high-resolution resonant inelastic soft x-ray scattering study of the quantum magnetic spin-chain materials Li2CuO2 and CuGeO3. By tuning the incoming photon energy to…
The dual nature of As-vacancies in LaFeAsO-derived superconductors: magnetic moment formation while preserving superconductivity
Konstantin Kikoin, Stefan-Ludwig Drechsler, Jiri Malek +1
As-vacancies (V_As) in La-1111-systems, which are nominally non-magnetic defects, are shown to create in their vicinity by symmetry ferromagnetically oriented local magnetic moment…
Disordered magnetism in superconducting KFe2As2 single crystals
V. Grinenko, S. -L. Drechsler, M. Abdel-Hafiez +10
High-quality KFe2As2 (K122) single crystals synthesized by different techniques have been studied by magnetization and specific heat (SH) measurements. There are 2 types of samples…
Thermodynamics of the two-dimensional frustrated J1-J2 Heisenberg ferromagnet in the collinear stripe regime: Susceptibility and correlation length
M. Härtel, J. Richter, O. Götze +2
We calculate the temperature dependence of the correlation length xi and the uniform susceptibility chi_0 of the frustrated J1-J2 square-lattice Heisenberg ferromagnet in the colli…
Full Relativistic Electronic Structure and Fermi Surface Sheets of the First Honeycomb-Lattice Pnictide Superconductor SrPtAs
Saad Elgazzar, A. M. Strydom, Stefan-Ludwig Drechsler
We report full-potential density functional theory (DFT)-based {\it ab initio} band structure calculations to investigate electronic structure properties of the first pnictide supe…
KFe2As2: coexistence of superconductivity and local moment derived spin-glass
V. Grinenko, M. Abdel-Hafiez, S. Aswartham +9
High-quality KFe2As2 single crystals have been studied by transport, magnetization and low-T specific heat measurements. Their analysis shows that superconductivity occurs (in some…
