摘要：

The structure and magnetic properties of Nd2AlFe15Mn compound have been investigated by means of x-ray diffraction and magnetization measurements. The Nd2AlFe15Mn compound has a rhombohedral Th2Zn17-type structure. The small thermal-expansion coefficient of Nd2AlFe15Mn compound was found by x-ray diffraction in temperature range of 103-342 K. Especially in the 282-342 K, the small thermal-expansion coefficient is nearly equal to zero. An anisotropic and strong positive spontaneous magnetostriction exists in Nd2AlFe15Mn compound. The magnetostrictive deformations were discussed. (c) 2005 American Institute of Physics.
