Results of a study of the magnetic properties of the intermetallic compound Y2 Ni7 and of the system Y2 (Ni, _ x Alx )7(x<0,\) indicate that in Y2 Ni7 the Fermi level is located in a region in which the density of states depends strongly on the energy. The temperature-induced ferromagnetism effect detected previously in Y2 Ni7 has not been observed.
