Weak Ferromagnetism in NiS under Nanocrystallization
Hayato Miyazaki, Tomohiko Yoshinaga, Ojiro Miyazaki +7
Structurally well-ordered NiS nanocrystals with an average diameter of nm retain the bulk-like two-step antiferromagnetic transitions, as shown by magnetization…
Survival of the metallic state in a single-hole multiband -orbital molecular system
Keisuke Matsui, Ryan A. Klein, Naoya Yoshikane +14
Strong correlations and ferromagnetic Hund's coupling lead to diverse electronic phenomena in transition-metal oxides that sensitively depend on the -orbital electron filling. F…
Robust Metal-Insulator Transition Despite Surface Dead-Layer Growth in Sub-10-nm Cr-Doped V2O3 Nanocrystals
Yoichi Ishiwata, Ichidai Harada, Masaki Imamura +9
We investigated the size dependence of the metal-insulator transition (MIT) in Cr-doped V2O3 nanocrystals by photoemission spectroscopy using complementary probing depths, together…
Narrowing band gap chemically and physically: Conductive dense hydrocarbon
Takeshi Nakagawa, Caoshun Zhang, Kejun Bu +14
Band gap energy of an organic molecule can be reduced by intermolecular interaction enhancement, and thus, certain polycyclic aromatic hydrocarbons (PAHs), which are insulators wit…
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…
Unusually strong electronic correlation and field-induced ordered phase in YbCo
J. Valenta, N. Tsujii, H. Yamaoka +10
We report the first study of electrical resistivity, magnetization, and specific heat on YbCo. The measurements on a single-phased sample of YbCo bring no evidence of magne…
Pressure-induced collapse of spin-orbital Mott state in the hyperhoneycomb iridate -LiIrO
T. Takayama, A. Krajewska, A. S. Gibbs +8
Hyperhoneycomb iridate -LiIrO is a three-dimensional analogue of two-dimensional honeycomb iridates, such as -LiIrO, which recently appeared as another playgr…
