摘要：
The crystal structure of a compound FeDy6Sb2 was determined by X-ray powder diffraction using the Rietveld method. The compound crystallizes in the hexagonal, space group P (6) over bar 2m (No. 189) with the Fe2P structure type and lattice parameters a=0.81449(5) nm, c=0.41641(3) nm, z = 1 and D-calc = 8.842 g/cm(3). The maximum magnetic entropy change Delta S-M for the compound is 3.41 J kg(-1) K-1 near its Curie temperature (143.4 K) on the magnetic field changes of 0-2.0 T. (c) 2006 Elsevier B.V.
