Abstract ：The structural, thermal expansion, and magnetic properties of the Nd$_{2}$Fe$_{16.5}$Cr$_{0.5}$ compound are investigated by means of x-ray diffraction and magnetization measurements. The Nd$_{2}$Fe$_{16.5}$Cr$_{0.5}$ compound has a rhombohedral Th$_{2}$Zn$_{17}$-type structure. There exists a small negative thermal expansion resulting from a spontaneous magnetostriction in the magnetic state of the Nd$_{2}$Fe$_{16.5}$Cr$_{0.5}$ compound. The average thermal expansion coefficient is $-1.06\times 10^{-6}$/K in a temperature range 299–394 K. The spontaneous magnetostrictive deformation and the Curie temperature are discussed.
