The low-field magnetic properties of polycrystalline Gd(Ni1-xTx)3 (T = Fe, Co) intermetallic compounds are presented. The whole system crystallizes in the rhombohedral PuNi3 type of crystal structure. The composition dependence of the Curie temperature TC(x) is associated with the change in the number of 3d electrons. Moreover, the field cooled and zero field cooled (FC-ZFC) curves at low applied magnetic field are related to the anisotropy of T element. The saturation magnetic moment MS(x) upon doping was estimated based on the hysteresis loops M(H).
