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…

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…

Stabilization of Nonmagnetic Hexagonal Close-Packed Phase in Nanocrystalline Nickel Metal with a Giant Volume Expansion
Sho Otsuru, Kenta Akashi, Miki Kakihara +11
Nanocrystalline Ni can adopt a hexagonal close-packed (hcp) structure,which does not appear in a bulk form under any conditions.Structural studies found its 20% expansion of vo…
