摘要：

Magnetoresistance (Delta rho/rho) measurements on a Ce(Fe0.96Al0.04)(2) compound in the temperature range 4.2-250 K and in magnetic fields up to 45 kOe are reported. The present study clearly suggests that in zero held, the low temperature state is an antiferromagnetic one, undergoing a metamagnetic transition to a ferromagnetic one in the temperature range 4.2-50 K at a characteristic field, (H-m) which decreases with increasing temperature.
