摘要：

Powder neutron diffraction measurements of the CeFe2Al8 compound at 1.5. 10 and 75 K indicate that this compound crystallizes in an orthorhombic crystal structure (space group Pbam). The crystal structure parameters of CeFe2Al8 were determined. The low temperature data at T = 1.5 K did not reveal magnetic ordering. The magnetization, magnetic susceptibility and the Mossbauer effect data indicate the existence of clusters of iron atoms below 6.5 K. (C) 2001 Elsevier Science B.V. All rights reserved.
