Pressure-dependent magnetization and magnetoresistivity studies on the tetragonal FeS (mackinawite): revealing its intrinsic metallic character
S. J. Denholme, H. Okazaki, S. Demura +9
The transport and magnetic properties of the tetragonal FeS were investigated using magnetoresistivity and magnetization within 2300 K, 70 kOe and $P\le…
On the bad metallicity and phase diagrams of Fe ( =Te, Se, S, solid solutions): an electrical resistivity study
M. ElMassalami, K. Deguchi, T. Machida +2
Based on a systematic analysis of the thermal evolution of the resistivities of Fe-based chalcogenides FeTe (= Se, S), it is inferred that their often obser…
Effect of high pressure annealing on the normal state transport of LaO0.5F0.5BiS2
I. Pallecchi, G. Lamura, M. Putti +6
We study normal state electrical, thermoelectrical and thermal transport in polycrystalline BiS2-based compounds, which become superconducting by F doping on the O site. In particu…
s-wave pairing in the optimally-doped LaO0.5F0.5BiS2 superconductor
G. Lamura, T. Shiroka, P. Bonfa +11
We report on the magnetic and superconducting properties of LaO0.5F0.5BiS2 by means of zero- (ZF) and transverse-field (TF) muon-spin spectroscopy measurements (uSR). Contrary to p…
Sulfur annealing effect for superconductivity in iron chalcogenide compounds
K. Deguchi, A. Yamashita, T. Yamaki +8
We discovered a novel annealing method for Fe-chalcogenide superconductors. It was found that sulfur annealing deintercalated excess Fe via formation of FeS2. Due to its specifics,…
Correlation between crystal structure and superconductivity in LaO0.5F0.5BiS2
Joe Kajitani, Keita Deguchi, Atsushi Omachi +6
Correlation between crystal structure and superconducting properties of the BiS2-based superconductor LaO0.5F0.5BiS2 was investigated. We have prepared LaO0.5F0.5BiS2 polycrystalli…
