Abstract: The compounds TbxGd1􀀀xNi3 with a PuNi3-type structure have been obtained. The magnetic properties have been investigated by using SQUID magnetometer (Quantum Design MPMS, temperature from 1.9 K to 300 K and magnetic eld up to 7 T). The partial replacement of Gd by Tb atoms is re ected in a decrease of the ordering temperature from 115 K (x = 0:0) to 81 K (x = 1:0) as well as the increase of the saturation magnetic moment MS from 6.93 B/f.u. (x = 0:0) to 7.14 B/f.u. (x = 1:0). A large di erence of M(T) curves has been noticed between the so-called eld cooling zero eld cooling magnetization. The thermomagnetic curves are sensitive to the applied magnetic eld and their origin can be understood as the domain-wall pinning e ect and as the temperature dependence of coercivity.
