概要
- 論文の詳細を見る
Atomic diffuse scattering intensity from a single crystal of fcc Pt-12.5 at.% Mn alloy was measured with the use of X-ray diffraction. Diffuse intensity maxima at 1/2 1/2 1/2 and its equivalent positions were observed in addition to diffuse intensity maxima at 100 and its equivalent positions on the diffraction patterns. The Warren-Cowley atomic short-range order parameters, α_lmn,i, were determined. At least, first 21 α_lmn parameters were needed to reproduce both kinds of diffuse maxima. The correlation length was about 14 A, indicating that the local fluctuation due to the ABC_6 type ordered structure still exists in the disordered state of Pt-12.5 at.% Mn alloy.
