- We have prepared a new system of $Gd_{1-x}Ce_xNi_5$ polycrystalline samples with concentrations x =0, 0.2, 0.5, and 0.8 in order to study the influence of different rare-earths substitutions on the ground state connected with spin fluctuations. GdNi₅ is a ferromagnetic compound with $T_{C}=31.8 K$ and CeNi₅ is a well-known spin fluctuation compound without magnetic ordering down to the lowest temperatures. X-ray diffraction study confirms the hexagonal crystal structure and the single phase samples. Magnetic properties (M(T),M(B)) show that an increasing content of Ce depresses the transition temperature, $T_{C}$, down to 4.9 K for x=0.8. The heat capacity measurements confirmed these results.
