Comparative study of superconducting and normal-state anisotropy in FeTeSe superconductors with controlled amounts of interstitial excess Fe
Yue Sun, Yongqiang Pan, Nan Zhou +8
We report a systematic study of the superconducting (SC) and normal-state anisotropy of FeTeSe single crystals with controlled amounts of excess Fe ( = 0…
Multilayered cuprate superconductor BaCaCuO(O,F) studied by temperature-dependent scanning tunneling microscopy and spectroscopy
Akira Sugimoto, Toshikazu Ekino, Alexander M. Gabovich +3
Scanning tunneling microscopy/spectroscopy (STM/STS) measurements were carried out on a multi-layered cuprate superconductor BaCaCuO(O,F). STM to…
Dynamics and mechanism of oxygen annealing in FeTeSe single crystal
Yue Sun, Yuji Tsuchiya, Toshihiro Taen +6
Iron chalcogenide Fe(Te,Se) attracted much attention due to its simple structure, which is favorable for probing the superconducting mechanism. Its less toxic nature compared with…
Hidden Superconductivity in Solid Solutions Sr(1-x)La(x)PbO3 detected by tunneling
V. A. Drozd, T. Ekino, A. M. Gabovich +2
Solid solutions of Sr1-xLaxPbO3 (x = 0, 0.05, 0.10, 0.15 and 0.20) were synthesized with the help of high pressure. Temperature (T) dependences of the resistivity r and differentia…
Electrical resistivity and tunneling anomalies in CeCuAs2
E. V. Sampathkumaran, T. Ekino, R. A. Ribeiro +9
The compound CeCuAs2 is found to exhibit negative temperature (T) coefficient of electrical resistivity (rho) under ambient pressure conditions in the entire T-range of investigati…
Formation of mid-gap states and ferromagnetism in semiconducting CaB
Jong-Soo Rhyee, B. H. Oh, B. K. Cho +5
We present a consistent overall picture of the electronic structure and ferromagnetic interaction in CaB, based on our joint transport, optical, and tunneling measurements on h…
