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…
Coexistence of bulk superconductivity and ferromagnetism in CeO1-xFxBiS2
Satoshi Demura, Keita Deguchi, Yoshikazu Mizuguchi +14
We show the observation of the coexistence of bulk superconductivity and ferromagnetism in CeO1-xFxBiS2(x = 0 - 1.0) prepared by annealing under high-pressure. In CeO1-xFxBiS2 syst…
Growth and superconducting properties of F-substituted ROBiS2 (R = La, Ce, Nd) single crystals
Masanori Nagao, Akira Miura, Satoshi Demura +6
F-substituted ROBiS2 (R = La, Ce, Nd) superconducting single crystals with different F concentration were grown successfully using CsCl/KCl flux. All the obtained single crystals h…
Structural Analysis and Superconducting Properties of F-Substituted NdOBiS2 Single Crystals
Masanori Nagao, Satoshi Demura, Keita Deguchi +6
F-substituted NdOBiS2 superconducting single crystals were grown using CsCl/KCl flux. This is the first example of the single-crystal growth of a BiS2-based superconductor. The obt…
Pressure-induced Enhancement of Superconductivity in BiS-layered LaOFBiS
Takahiro Tomita, Masaya Ebata, Hideto Soeda +9
The newly discovered BiS-based LaOFBiS (=0.5) becomes superconductive at =2.5 K. Electrical resistivity and magnetization measurements are performed u…
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,…
