Magnetoresistance and magnetization studies of the Laves-phase compound Ce(${\mathrm{Fe}}_{0.92}$${\mathrm{Al}}_{0.08}$${)}_2$

A detailed study of magnetoresistance and magnetization is reported on the Laves-phase compound Ce(${\mathrm{Fe}}_{0.92}$ ${\mathrm{Al}}_{0.08}$ ${)}_2$ 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.
