The magnetization, ac susceptibility and the lattice parameter have be
en studied in the series of the Ce1-xYxFe2 (0.0 less than or equal to
x less than or equal to 1.0) and (Ce(0.8)R(0.2))(Fe1-xAlx)(2) (R = Y,
Lu, Gd and Sm) compounds. The various magnetic behaviors are discussed
in terms the delocalised character of Ce 4f-electron.
