Probing the direct factor for superconductivity in FeSe-Based Superconductors by Raman Scattering
Anmin Zhang, Xiaoli Ma, Yimeng Wang +7
The FeSe-based superconductors exhibit a wide range of critical temperature Tc under a variety of material and physical conditions, but extensive studies to date have yet to produc…
Enhanced superconductivity and anisotropy of FeTe0.6Se0.4 single crystals with Li-NH3 intercalation
Chenghe Li, Shanshan Sun, Shaohua Wang +1
We report a systematic study of anisotropy resistivity, magnetoresistance and Hall effect of Li0.32(NH3)yFe2Te1.2Se0.8 single crystals. When compared to the parent compound FeTe0.6…
Critical current density and vortex pinning mechanism of Lix(NH3)yFe2Te1.2Se0.8 single crystals
Shaohua Wang, Shanshan Sun, Hechang Lei
We grew Lix(NH3)yFe2Te1.2Se0.8 single crystals successfully using the low-temperature ammonothermal method and the onset superconducting transition temperature Tc,onset is increase…
Extreme anisotropy and anomalous transport properties of heavily electron doped Lix(NH3)yFe2Se2 single crystals
Shanshan Sun, Shaohua Wang, Rong Yu +1
The missing hole packets near the Brillouin zone center render unique electronic structures to the heavily electron doped FeSe-based superconductors with Tc above 40 K. It challeng…
Transport properties of Lix(NH3)yFe2(TezSe1-z)2 single crystals in the mixed state
Shanshan Sun, Shaohua Wang, Chenghe Li +1
We study the electric transport properties of Lix(NH3)yFe2(TezSe1-z)2 single crystals with z= 0 and 0.6 in the mixed state. Thermally-activated flux-flow, vortex glass and flux-flo…
Robust short-range-ordered nematicity in FeSe evidenced by high-pressure NMR
P. S. Wang, P. Zhou, S. S. Sun +5
We report high-pressure Se NMR studies on FeSe single crystals that reveal a prominent inhomogeneous NMR linewidth broadening upon cooling, with the magnetic field applied a…
Type-I superconductivity in KBi2 single crystals
Shanshan Sun, Kai Liu, Hechang Lei
We report the detailed transport, magnetic, thermodynamic properties and theoretical calculation of KBi2 single crystals in superconducting and normal states. KBi2 shows metallic b…
