Ce(Fe[sub 1-x]A1[sub x])[sub 2], with x = 0, 0.06 and 0.14 has been studied by small-angle neutron scattering (SANS) in order to investigate the instability of the ferromagnetic state in the pure material to small mounts of magnetic disorder. The pure material (x = 0) displays a ferromagnetic transition near T[sub C] = 225 K, and more complicated behavior below [approximately] 100 K. The disordered alloys, x = 0.06 and x = 0.14, display ferromagnetic-like states over relatively narrow temperature ranges, an additional low temperature phase. The ferromagnetic-like state in the x = 0.14 alloys appears to be qualitatively different to that exhibited by the other two. High wavevector-resolution measurements on the x = 0.06 sample indicate that its low temperature ordered phase is ferrimagnetic in origin.
