The structural and magnetic properties of the Nd2 Co17-x Mnx (x ≤ 14) compounds have been investigated bymeans of x-ray diffraction and magnetization measurements. The Nd2Co17-xMnx (x ≤ 14) compounds have arhombohedral Th2Znl7-type structure. The unit-cell volume increases with increasing x. The Curie temperatureand the saturation magnetization of these compounds show a marvellous drop with increasing x. The spinreorientation is observed at about 190 K in the Nd2Co15Mn2 compound.
