In 2012, we discovered superconductivity in Bi4O4S3 and LaO1− x F x BiS2, whose crystal
structures are composed of alternate stacks of a BiS2-type conduction layer and a blocking …

BiS2-based layered superconductors have attracted considerable interest owing to the
relatively large spin–orbit coupling of bismuth 6 p orbitals, the strong coupling nature by …

Centrosymmetric compounds with local inversion symmetry breaking have tremendously
interesting and intriguing physical properties. In this study, we focus on a BiCh2-based (Ch …

We report the sulfur isotope effect on transition temperature (T c) in a BiS 2-based
superconductor Bi 4 O 4 S 3. Polycrystalline samples of Bi 4 O 4 S 3 were prepared using 32 …

Abstract BiCh 2-based (Ch: S, Se) layered superconductors have attracted extensive

We have investigated the in-plane anisotropy of the c-axis magnetoresistance for single
crystals of a BiCh2-based superconductor LaO0. 5F0. 5BiSSe under in-plane magnetic …

The family of BiS2-based superconductors has attracted considerable attention since their
discovery in 2012 due to the unique structural and electronic properties of these materials …

Recently, two-fold symmetric in-plane anisotropy of the superconducting properties have
been observed in a single crystal of BiCh 2-based (Ch: S, Se) layered superconductor LaO …

Investigation of isotope effects on superconducting transition temperature (T c) is one of the
useful methods to examine whether electron–phonon interaction is essential for pairing …

In this study, we investigate the bulk electronic structure of Pb-substituted LaO 0.5 F 0.5 BiS
2 single crystals, using two types of hard x-ray spectroscopy. High-energy-resolution …
