- 論文の詳細を見る
A new intermetallic compound, MnGa_2Sb_2, has been synthesized by direct reaction from Mn and GaSb at 6GPa and 500℃ for 30min using a belt-type high pressure apparatus. The compound crystallizes into an orthorhombic structure with the space group Iba2 (No. 45). The structure was refined by the Rietveld analysis of the powder X-ray diffraction data and the lattice constant was determined to be a=1.180(7)nm, b=0.5968(2)nm, c=0.5858(2)nm. The structure consists of -Mn-Mn-Mn- linear chains parallel to the c-axis. The compound exhibits metallic conductivity and itinerant-electron ferromagnetic behavior with the Curie temperature of 310K.
