Possible Phase Separation and Transport Properties in Large Superconducting Ca0.77La0.18Fe0.90As2 Crystals
W. Zhou, J. C. Zhuang, F. F. Yuan +4
We synthesized large superconducting single crystal Ca0.77La0.18Fe0.90As2 ('112' type) of 2 millimeter size. Scanning electron microscopy (SEM) measurements revealed that bright an…
Bulk Superconductivity in FeTeSe Induced by Annealing in Se and S Vapor
Yue Sun, Yuji Tsuchiya, Tatsuhiro Yamada +4
We reported that bulk superconductivity in FeTeSe can be induced by annealing in Se and S vapor. The well-annealed samples show a large critical current densi…
Magnetic relaxation and collective vortex creep in FeTeSe single crystal
Yue Sun, Toshihiro Taen, Yuji Tsuchiya +3
We study the vortex dynamics in high-quality FeTeSe single crystal by performing magnetization measurements of the screening current density \emph{J} and flux c…
Coexistence of two superconducting phases in Ca1-xLaxFe2As2
Y. Sun, W. Zhou, L. J. Cui +5
Single crystals of Ca1-xLaxFe2As2 for x ranging from 0 to 0.25 have been grown and characterized by structural, transport and magnetic measurements. Coexistence of two superconduct…
Upper Critical Fields and Anisotropy of Ca1-xLaxFe2As2 Single Crystals
W. Zhou, F. F. Yuan, J. C. Zhuang +5
Superconductivity of Ca1-xLaxFe2As2 single crystals with various doping level were investigated via electromagnetic measurements for out-plane (H//c) and in-plane (H//ab) direction…
Evolution of Superconductivity in FeTeSe Annealed in Te Vapor
Yue Sun, Yuji Tsuchiya, Tatsuhiro Yamada +4
We report a detailed study of the Te vapor annealing effect in FeTeSe single crystals. Bulk superconductivity can be gradually induced by annealing with inc…
