Superconductivity of Electron-Doped NdOBiS2 by Substitution of Mixed-Valence Ce ions

Autor: Kase, Naoki, Matsumoto, Masaya, Kondo, Katsuo, Gouchi, Jun, Uwatoko, Yoshiya, Sakakibara, Toshiro, Miyakawa, Nobuaki

Publikováno v: J. Phys. Soc. Jpn. 88, 103703 (2019)

Superconductivity is achieved in Nd1-xCexOBiS2 via electron doping using mixed-valence Ce ions. Single crystals with x = 0.2, 0.3, 0.4, and 0.5 are generated using a CsCl flux method. Plate-like single crystals with dimensions of 0.8 0.8 0.2 mm3 were

Autor: Tohyama, Takami, Ogura, Riku, Yoshinaga, Kensuke, Naito, Shin, Miyakawa, Nobuaki, Kaneshita, Eiji

Publikováno v: J. Phys. Chem. Solids, 127, 252-257 (2019)

We synthesize a new titanium-oxide compound AlTi2O5 with pseudobrookite-type structure. The formal valence of Ti is 3.5+ that is the same as the Magneli compound Ti4O7 and the spinel compound LiTi2O4. AlTi2O5 exhibits insulating behavior in resistivi

Coexistence of superconductivity and charge-density wave in the quasi-one-dimensional material HfTe3

Autor: Denholme, Saleem J., Yukawa, Akinori, Tsumura, Kohei, Nagao, Masanori, Tamura, Ryuji, Watauchi, Satoshi, Tanaka, Isao, Takayanagi, Hideaki, Miyakawa, Nobuaki

Publikováno v: Scientific Reports 7, Article number: 45217 (2017)

We present the first experimental evidence for metallicity, superconductivity (SC) and the co-existence of charge density waves (CDW) in the quasi-one-dimensional material HfTe3. The existence of such phenomena is a typical characteristic of the tran
