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 …

We synthesized new REO 0.5 F 0.5 BiS 2 (RE: rare earth) superconductors with high-
entropy-alloy-type (HEA-type) REO blocking layers. The lattice constant a systematically …

In 2012, a new layered superconductor where BiS 2 layer is the superconducting layer was
discovered. So far, seven types of BiS 2-based superconductors and two related …

The newly discovered superconductivity in infinite-layer nickelate superconducting films has
attracted much attention, largely because their crystalline and electronic structures are …

Conventional Rashba spin polarization is caused by the combination of strong spin–orbit
interaction and spatial inversion asymmetry. However, Rashba–Dresselhaus-type spin-split …

We show the observation of the coexistence of bulk superconductivity and magnetic
ordering in CeO1− x F x BiS2 (x= 0–1.0) prepared by annealing under high pressure. In the …

A novel family of superconductors based on BiS 2-based superconducting layers were
discovered in 2012. In short order, other BiS 2-based superconductors with the same or …

We have investigated the Se isotope effect in the layered bismuth chalcogenide (BiC h 2-
based) superconductor La O 0.6 F 0.4 Bi (S, Se) 2 with Se 76 and Se 80. For all examined …

In cuprate superconductors, the Hg-, Tl-and Bi-based systems with multilayers of CuO 2
planes within one unit cell usually have critical temperatures higher than 100 K. However …
