Photo-induced phase transition on black samarium monosulfide
Hiroshi Watanabe, Yusuke Takeno, Yusuke Negoro +14
To investigate the role of the excitons for the origin of the pressure-induced phase transition (BGT) from the black-colored insulator (BI) to the golden-yellow-colored metal (GM)…
Anomalous magnetic transition in a disordered quasicrystal approximant with heavy-fermion nature
Takayuki Shiino, Farid Labib, Yuma Hirano +7
Quasicrystal approximant (CexY1-x)Cd6 (0 < x < 1) forms a network of corner-sharing octahedra. We report that (Ce0.8Y0.2)Cd6 exhibits an anomalous magnetic transition which can be…
Variation of Pressure-Induced Valence Transition with Approximation Degree in Yb-Based Quasicrystalline Approximants
Keiichiro Imura, Yuki Yoneyama, Hideyuki Ando +6
We have synthesized new Tsai-type Yb-based intermediate-valence approximant crystals (ACs) with different degree of approximation to quasicrystal, Zn--Au--Yb 1/1 and 2/1 AC, and st…
Current-Induced Metallization and Valence Transition in Black SmS
Shin-ichi Kimura, Hiroshi Watanabe, Shingo Tatsukawa +4
A strongly-correlated insulator, samarium mono-sulfide (SmS), presents not only the pressure-induced insulator-to-metal transition (IMT) with the color change from black to golden-…
Superconductivity at the Pressure-Induced Ferromagnetic Critical Region in UCoGe
Masahiro Manago, Shunsaku Kitagawa, Kenji Ishida +3
The phase separation of the ferromagnetic (FM) and paramagnetic (PM) phases in the superconducting (SC) state of UCoGe at the FM critical region was investigated using Co nu…
Spin-triplet superconductivity in the paramagnetic UCoGe under pressure studied by Co NMR
Masahiro Manago, Shunsaku Kitagawa, Kenji Ishida +3
A Co nuclear magnetic resonance (NMR) measurement was performed on the single-crystalline ferromagnetic (FM) superconductor UCoGe under a pressure of 1.09 GPa, where the FM…
