摘要：

A detailed study of magnetoresistance and magnetization is reported on the Laves-phase compound Ce(Fe0.92Al0.08)2 in the temperature range of 4.4 to 250 K and in magnetic fields up to 45 kOe. The measurements indicate a paramagnetic to ferromagnetic transition at 170 K and rule out the possibility of a spin-glass transition as had been earlier reported in some studies. The magnetoresistance measurements clearly indicate that the compound has an antiferromagnetic state below 100 K as suggested by earlier neutron-scattering measurements. The antiferromagnetic state is found to undergo a metamagnetic transition which could be observed in the present study above 60 K.
