- 論文の詳細を見る
The search for a perovskite-type new boride in the Sc–Ni–B system has been carried out by the arc-melting synthetic method. As a result, the chemical formula of the compound ScNi3B0.5 was obtained for the first time. This compound has the cubic perovskite-type structure (space group: Pm3m) with the lattice parameter $a{=}0.37760(7)$ nm. ScNi3B0.5 exhibits metallic behavior down to 4.2 K. The magnetic susceptibility of ScNi3B0.5 shows Pauli paramagnetism. No superconductivity appears down to the lowest temperature as determined by electric and magnetic measurements. The micro-Vickers hardness and oxidation resistivity in air are also reported for ScNi3B0.5.
