Superconducting Order from Disorder in 2H-TaSe $_{2 - x}$ S $_{x}$ (0 $\leq$ x $\leq$ 2)

Lijun Li, Xiaoyu Deng, Zhen Wang +12

We report on the emergence of robust superconducting order in single crystal alloys of 2H-TaSe $_{2 - x}$ S $_{x}$ (0 $\leq$ x $\leq$ 2) . The critical temperature of the alloy is surprisin…

Enhancement of the thermoelectric properties in doped FeSb $_{2}$ bulk crystals

Kefeng Wang, Rongwei Hu, John Warren +1

Kondo insulator FeSb $_{2}$ with large Seebeck coefficient would have potential in thermoelectric applications in cryogenic temperature range if it had not been for large thermal cond…

Critical current density and vortex pinning in tetragonal FeS $_{1 - x}$ Se $_{x}$ ( $x = 0, 0.06$ )

Aifeng Wang, Lijun Wu, V. N. Ivanovski +4

We report critical current density ( $J_{c}$ ) in tetragonal FeS single crystals, similar to iron based superconductors with much higher superconducting critical temperatures ( $T_{c}$ '…

Sustained phase separation and spin glass in Co-doped K $_{x}$ Fe $_{2 - y}$ Se $_{2}$ single crystals

Hyejin Ryu, Kefeng Wang, M. Opacic +5

We present Co substitution effects in K $_{x}$ Fe $_{2 - y - z}$ Co $_{z}$ Se $_{2}$ (0.06 $\leq$ $z$ $\leq$ 1.73) single crystal alloys. By 3.5\% of Co doping superconductivity is suppressed…
