Abstract: We present the results of an experimental study focused around CeNi5 in the CexGd1??xNi5 system. Pseudobinary bulk samples were prepared with concentration of x = 0:85, 0.9, 0.95, and 0.97 by arc melting method. The structural analysis confirmed the CaCu5 hexagonal crystal structure with P6/mmm space group and proved the existence of a single phase in all of them. The measurement of the magnetic properties shows that the increase of the Ce content leads to lower TC values. Above x = 0:9 spin fluctuations behaviour appears with a shoulder in M(T) around T = 130 K. Heat capacity measurements support these observations.
