Optimization of a Non-arsenic Iron-based Superconductor for Wire Fabrication
Jonathan E. Mitchell, Daniel A. Hillesheim, Craig A. Bridges +5
We report on the optimization of synthesis of iron-selenide (non-arsenic) superconducting powders that are based on '122' composition, with optimal Tc = 38 K and Jc = 10^5 A/cm2 (4…
Orbital occupancy and charge doping in iron-based superconductors
Claudia Cantoni, Jonathan E. Mitchell, Andrew F. May +9
Iron-based superconductors (FBS) comprise several families of compounds having the same atomic building blocks for superconductivity, but large discrepancies among their physical p…
Local inhomogeneity and filamentary superconductivity in Pr-doped CaFeAs
Krzysztof Gofryk, Minghu Pan, Claudia Cantoni +3
We use multi-scale techniques to determine the extent of local inhomogeneity and superconductivity in CaPrFeAs single crystal. The inhomogeneity is ma…
The influence of spin fluctuations on the thermal conductivity in superconducting Ba(Fe_{1-x}Co_x)_2As_2
Andrew F. May, Michael A. McGuire, Jonathan E. Mitchell +2
The thermal conductivity of electron-doped Ba(FeCo)As single crystals is investigated below 200K, with an emphasis on the behavior near the magnetic and superco…
Temperature-composition Phase Diagrams for Ba1-xSrxFe2As2 and Ba0.5Sr0.5(Fe1-yCoy)2As2
Jonathan E. Mitchell, Bayrammurad Saparov, Wenzhi Lin +6
Single crystals of mixed alkaline earth metal iron arsenide materials of Ba1-xSrxFe2As2 and Ba0.5Sr0.5(Fe1-yCoy)2As2 are synthesized via the self-flux method. Ba1-xSrxFe2As2 displa…
Pressure Induced Superconductivity in Ba0.5Sr0.5Fe2As2
Georgiy M. Tsoi, Walter Malone, Walter Uhoya +5
High-pressure electrical resistance measurements have been performed on single crystal Ba0.5Sr0.5Fe2As2 platelets to pressures of 16 GPa and temperatures down to 10 K using designe…
