Synthesis, crystal structure and magnetism of beta-Fe1.00(2)Se1.00(3) single crystals
Rongwei Hu, Hechang Lei, Milinda Abeykoon +5
Understanding iron based superconductors requires high quality impurity free single crystals. So far they have been elusive for beta-FeSe and extraction of intrinsic materials prop…
Antiferromagnetism in semiconducting KFe0.85Ag1.15Te2 single crystals
Hechang Lei, Emil S. Bozin, Kefeng Wang +1
We have synthesized single crystals of K1.00(3)Fe0.85(2)Ag1.15(2)Te2.0(1). The materials crystallizes in the ThCr2Si2 structure with I4/mmm symmetry and without K and Fe/Ag deficie…
Phase Diagram of KxFe2-ySe2-zSz and the Suppression of its Superconducting State by an Fe2-Se/S Tetrahedron Distortion
Hechang Lei, Milinda Abeykoon, Emil S. Bozin +3
We report structurally tuned superconductivity in KxFe2-ySe2-zSz (0<=z<=2) phase diagram. Superconducting Tc is suppressed as S is incorporated into the lattice, eventually vanishi…
Spin glass behavior of insulating K0.8Fe2-xS2
Hechang Lei, Milinda Abeykoon, Emil S. Bozin +1
We report the discovery of KxFe2-yS2 single crystals, isostructural to KxFe2-ySe2 superconductors. The sulfide compound is a small gap semiconductor and shows spin-glass behavior b…
