摘要：

Using x-ray diffraction and magnetic measurements, we have studied the structural and magnetic properties of Dy2Co17-xMnx (x=0similar to5) compounds with a rhombohedral Th2Zn17-type structure. With an increasing Mn concentration x, the unit-cell volume V was found to increase linearly. The Curie temperature T-C decreases linearly, and the saturation magnetization M-s at 5K first increases slightly for x <1, then decreases rapidly for x >1 with a further increase of Mn concentration x. In compounds for x=1similar to3, a spin reorientation was found, A magnetic diagram of the compounds is given.
