Coexistence of 3d-ferromagnetism and superconductivity in [(Li(1-x)Fex)OH](Fe(1-y)Liy)Se
Ursula Pachmayr, Fabian Nitsche, Hubertus Luetkens +5
Superconducting [(Li(1-x)Fex)OH](Fe(1-y)Liy)Se (x ~ 0.2, y ~ 0.08) was synthesized by hydrothermal methods and structurally characterized by single crystal X-ray diffraction. The c…
Superconductivity by transition metal doping in Ca(FeMAs)(PtAs) (M = Co, Ni, Cu)
Tobias Stürzer, Fabian Kessler, Dirk Johrendt
We report the successful substitution of cobalt, nickel, and copper for iron in the 1038 phase parent compound Ca(FeAs)(PtAs) yielding Ca(FeCo$…
Superconductivity by rare earth doping in the 1038-type compounds (CaRE)(FeAs)(PtAs) with RE = Y, La-Nd, Sm-Lu
Tobias Stürzer, Gerald Derondeau, Dirk Johrendt
We report superconductivity in polycrystalline samples of the 1038-type compounds (CaRE)(FeAs)(PtAs) up to T = 35 K with RE = Y, La-Nd, Sm, Gd…
The role of different negatively charged layers in Ca10(Fe1-xPtxAs)10(Pt3+yAs8) and superconductivity at 30 K in electron-doped (Ca0.8La0.2)10(FeAs)10(Pt3As8)
Tobias Stürzer, Gerald Derondeau, Dirk Johrendt
The recently discovered compounds Ca10(Fe1-xPtxAs)10(Pt3+yAs8) exhibit superconductivity up to 38 K, and contain iron arsenide (FeAs) and platinum arsenide (Pt3+yAs8) layers separa…
The interplay of electron doping and chemical pressure in Ba(Fe(1-y)Coy)2(As(1-x)Px)2
Veronika Zinth, Dirk Johrendt
The effects of internal chemical pressure on electron doped iron arsenide superconductors are studied in the series Ba(Fe(1-y)Coy)2(As(1-x)Px)2. Combinations of both dopants induce…
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…
