Competition of magnetism and superconductivity in underdoped (Ba1-xKx)Fe2As2
Marianne Rotter, Marcus Tegel, Inga Schellenberg +7
Polycrystalline samples of underdoped (Ba1-xKx)Fe2As2 (x<=0.4) were synthesized and studied by x-ray powder diffraction, magnetic susceptibility, specific heat and 57Fe-Moessbauer-…
Superconductivity and Crystal Structures of (Ba1-xKx)Fe2As2 (x = 0 - 1)
Marianne Rotter, Michael Pangerl, Marcus Tegel +1
We report on doping dependencies of structural parameters and superconducting transition temperatures in the solid solution (Ba1-xKx)Fe2As2. As the main effect of doping on the cry…
Inelastic neutron scattering and lattice dynamical calculations in BaFe2As2
R. Mittal, Y. Su, S. Rols +6
We report here first extensive measurements of the temperature dependence of phonon density of states of BaFe2As2, the parent compound of the newly discovered FeAs-based supercondu…
Neutron diffraction on antiferromagnetic ordering in single-crystal BaFe2As2
Y. Su, P. Link, A. Schneidewind +9
Neutron diffraction experiments have been carried out on a Sn-flux grown BaFe2As2 single crystal, the parent compound of the A-122 family of FeAs-based high-Tc superconductors. A t…
Spin density wave anomaly at 140 K in the ternary iron arsenide BaFe2As2
Marianne Rotter, Marcus Tegel, Inga Schellenberg +3
The ternary iron arsenide BaFe2As2 with the tetragonal ThCr2Si2-type structure exhibits a spin density wave (SDW) anomaly at 140 K, very similar to LaFeAsO, the parent compound of…
Structural and magnetic phase transitions in the ternary iron arsenides SrFe2As2 and EuFe2As2
Marcus Tegel, Marianne Rotter, Veronika Weiss +3
The structural and magnetic phase transitions of the ternary iron arsenides SrFe2As2 and EuFe2As2 were studied by temperature-dependent x-ray powder diffraction and 57-Fe Moessbaue…
