摘要
The structural,thermal expansion,and magnetic properties of the Nc/2^16.5^0.5 compound are investigated by means of x-ray diffraction and magnetization measurements.The Nd2^616.560.5 compound has a rhombohedral Th2Znn-type structure.There exists a small negative thermal expansion resulting from a spontaneous magnetostriction in the magnetic state of the^2^16.5 Cr0.5 compound.The average thermal expansion coefficient is-1.06×10^6/K in a temperature range 299-394 K.The spontaneous magnetostrictive deformation and the Curie temperature are discussed.
