It is found that the expansion of the low-temperature specific heat C p of the antiferromagnetic metallic compounds GdCu, GdCu2, and GdCu5 contains a large term that is proportional to the square of temperature (δT 2). The value of δ is inversely proportional to the Néel temperature T N. The GdCu2 compound exhibits a strong dependence of the specific heat anomaly at T N on an external magnetic field. The results obtained are compared with the data for other metal antiferromagnets, for example, the CuMnSb Heusler alloy.
