中文摘要The structure and the magnetic properties of the Gd5Sn4 compound have been investigated by means of X-ray diffraction (XRD) and magnetization measurements. Temperature dependent XRD investigation reveals that there is no structural transition around the temperature at which the first-order magnetic transition occurs in this compound, i.e. the compound retains the Sm5Ge4-type structure from 80 K(T-C), which is different from the Gd-5(Si, Ge)(4) system. Based on the Rietveld refinement of the XRD pattern of Gd5Sn4 compound, we show that the unit cell volume exhibits a dip near the Curie temperature, i.e. a negative coefficient of thermal expansion alpha approximate to -1.5 x 10(-4) K-1 from 82 to 90 K and a positive coefficient alpha approximate to 2.2 x 10(-4) K-1 from 90 to 98 K. The coefficient of thermal expansion from 98 to 298 K is only 2.5 x 10(-5) K-1. (C) 2003 Elsevier B.V. All rights reserved.
