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…
Multiple Superconducting Phases in Palladium Deuteride Induced by Nuclear-Spin Isotope Effect
Ryoma Kato, Ten-ichiro Yoshida, Riku Iimori +5
We study the superconducting properties of high-quality PdD films. The resistivity shows a sharp drop at 1.7 K, marking the superconducting transition. However, a 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…
New quantum state formed by highly concentrated protons in superconducting palladium hydride
Ryoma Kato, Ten-ichiro Yoshida, Riku Iimori +6
Hydrogen exhibits quantum phenomena, such as tunneling in materials. According to theory, the quantum properties of hydrogen change significantly in superconductors due to the emer…
Unusual Low-Temperature Phase in VO Nanoparticles
Y. Ishiwata, S. Suehiro, M. Hagihala +4
We present a systematic investigation of the crystal and electronic structure and the magnetic properties above and below the metal-insulator transition of ball-milled VO nanop…
