Critical fields, thermally-activated transport and critical current density of beta-FeSe single crystals
Hechang Lei, Rongwei Hu, C. Petrovic
We present critical fields, thermally-activated flux flow (TAFF) and critical current density of tetragonal phase beta-FeSe single crystals. The upper critical fields Hc2(T) for H|…
Raising Tc in charge density wave superconductor ZrTe3 by Ni intercalation
Hechang Lei, Xiangde Zhu, C. Petrovic
We report discovery of bulk superconductivity in Ni0.05ZrTe3 at Tc = 3.1 K, obtained through Ni intercalation. Superconductivity coexists with charge density wave (CDW) state with…
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…
Coexistence of bulk superconductivity and charge density wave in CuxZrTe3
Xiangde Zhu, Hechang Lei, C. Petrovic
We report coexistence of bulk superconductivity and charge density wave (CDW) with superconducting critical temperature Tc = 3.8 K in Cu intercalated quasi-two-dimensional crystals…
Anisotropy in transport and magnetic properties of K0.64Fe1.44Se2
Hechang Lei, C. Petrovic
We report a study of anisotropy in transport and magnetic properties of K0.64Fe1.44Se2.00 single crystals. The anisotropy in resistivity is up to one order of magnitude between 1.8…
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…
