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…
Fermionic Order by Disorder in a van der Waals Antiferromagnet
R. Okuma, D. Ueta, S. Kuniyoshi +11
CeTe3 is a unique platform to investigate the itinerant magnetism in a van der Waals (vdW) coupled metal. Despite chemical pressure being a promising route to boost quantum fluctua…
