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…
Electric field enhancement of the superconducting spin-valve effect via strain-transfer across a ferromagnetic/ferroelectric interface
Tomohiro Kikuta, Sachio Komori, Keiichiro Imura +1
In a ferromagnet/superconductor/ferromagnet (F/S/F) superconducting spin-valve (SSV), a change of the magnetization alignment of the two F layers modulates the critical temperature…
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-…
Photo-induced nonlinear band shift and valence transition in SmS
Yitong Chen, Takuto Nakamura, Hiroshi Watanabe +12
The photo-induced band structure variation of a rare-earth-based semiconductor, samarium monosulfide (SmS), was investigated using high-harmonic-generation laser-based time-resolve…
