Synthesis, Crystal Structure and Magnetism of Eu3Sc2O5Fe2As2
Franziska Hummel, Marcus Tegel, Birgit Gerke +2
The iron arsenide Eu3Fe2O5Fe2As2 was synthesized at 1173-1373 K in a resistance furnace and characterized by X-ray powder diffraction with Rietveld analysis: Sr3Fe2O5Cu2S2-type, I4…
Superconductivity up to 35 K in the iron-platinum arsenides (CaFe1-xPtxAs)10Pt4-yAs8 with layered structures
Catrin Löhnert, Tobias Stürzer, Marcus Tegel +3
We report the synthesis and crystal structures of three new superconducting iron-platinum arsenides (CaFe1-xPtxAs)10Pt4-yAs8 (x = 0-0.15, y = 0-0.4). The structures are stacking va…
Suppression of superconductivity by V-doping and possible magnetic order in Sr2VO3FeAs
Marcus Tegel, Tanja Schmid, Tobias Stürzer +4
Superconductivity at 33 K in Sr2VO3FeAs is completely suppressed by small amounts of V-doping in Sr2VO3[Fe0.93(+/-0.01)V0.07(+/-0.01)]As. The crystal structures and exact stoichiom…
The crystal structure of FeSe0.44Te0.56
Marcus Tegel, Catrin Loehnert, Dirk Johrendt
The crystal structure of the superconductor FeSe0.44Te0.56 was redetermined by high-resolution X-ray single crystal diffraction at 173 K (anti-PbO-type, P4/nmm, a=3.7996(2), c=5.98…
Low Temperature Crystal Structure and 57Fe Moessbauer Spectroscopy of Sr3Sc2O5Fe2As2
Marcus Tegel, Inga Schellenberg, Franziska Hummel +2
The crystal structure of the layered iron arsenide Sr3Sc2O5Fe2As2 was determined between 300 and 10 K. The lattice parameters of the tetragonal cell decrease anisotropically accord…
The layered iron arsenides Sr2CrO3FeAs and Ba2ScO3FeAs
Marcus Tegel, Franziska Hummel, Sebastian Lackner +3
Polycrystalline samples of the layered iron arsenides Sr2CrO3FeAs and Ba2ScO3FeAs were synthesized by high temperature solid state reactions and their crystal structures determined…
