Coupled Magnetic and Superconducting Transitions in SrVOFeAs Under Pressure
S. Holenstein, F. Hummel, Z. Guguchia +11
We report muon spin rotation (SR) and magnetization measurements on superconducting SrVOFeAs under pressure. At ambient pressure, SrVOFeAs undergoes an a…
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…
Weak magnetism and the Mott-state of vanadium in superconducting Sr2VO3FeAs
Franziska Hummel, Yixi Su, Anatoliy Senyshyn +1
We report neutron scattering data and DFT calculations of the stoichiometric iron-arsenide superconductor Sr2VO3FeAs. Rietveld refinements of neutron powder patterns confirm the id…
Non-stoichiometry and the magnetic structure of Sr2CrO3FeAs
Marcus Tegel, Franziska Hummel, Yixi Su +3
The iron arsenide Sr2CrO3FeAs with the tetragonal Sr2GaO3CuS-type structure was synthesized and its crystal structure re-determined by neutron powder diffraction. In contrast to pr…
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…
