Sb- and Se-substituted CeOBiS2 single crystals have been successfully grown using CsCl/KCl flux. Sb and Se substitution dependence of the superconductivity on CeOBiS2 was investigated and the superconducting phase diagram at above 0.3 K was described

Predictive power of polynomial machine learning potentials for liquid states in 22 elemental systems
The polynomial machine learning potentials (MLPs) described by polynomial rotational invariants have been systematically developed for various systems and used in diverse applications in crystalline states. In this study, we systematically investigat

Sb-substituted CeOBiS2 single crystals with 0.2-1.0 mm size have been successfully grown using CsCl/KCl flux. Sb substitution strongly suppressed the superconductivity in CeOBiS2, and the substitution of more than approximately 4 atomic percent in Bi

A spin space group provides a suitable way to fully exploit the symmetry of a spin arrangement with a negligible spin-orbit coupling. There has been a growing interest in applying spin symmetry analysis with the spin space group in the field of magne

Superconductors are influenced by high-entropy alloys (HEAs); these have been investigated in various functional materials. REOBiS$_2$ (RE = La, Ce, Pr, Nd, Sm, and Gd in different combinations) single crystals with HEAs at the RE-site were successfu

Single-crystal whiskers of REBa2Cu3Ox (RE-123, RE: rare earth element) cuprate superconductors were successfully grown using Te-doped precursors utilizing the concept of high-entropy-alloys (HEAs) at the RE site. The obtained whiskers were 0.5-1.0 mm

Single crystals of Ce-doped (La,Pr)OBiS2 superconductors, multinary rare-earth elements substituted ROBiS2, were successfully grown. The grown crystals typically had a size of 1-2 mm and a plate-like shape with a well-developed c-plane. The c-axis la

Longitudinal-optical (LO) mode phonon branches of KCl and NaCl were measured using inelastic X-ray scattering (IXS) at 300 K and calculated by the first-principles phonon calculation with the stochastic self-consistent harmonic approximation. Spectra
