The effect of Pr, Nd addition on the magnetic properties and magnetic exchange interaction of gadolinium alloys was systematically studied. Curie temperature TC and magnetic moment of Gd1–xREx (RE=Pr, Nd) systems with x<0.05 were investigated. When x<0.05, Pr and Nd formed respectively with Gd continuous solid solution which has the crystalline structure HCP. Study on the magnetic behavior indicated that at near room temperature, the simple ferromagnetism prevailed in these two systems of alloy. The Curie temperature and magnetic moment of Gd1–xREx alloy decreased with RE (RE= Pr, Nd) content x increasing. The de Gennes factor of Gd1–xREx alloy which was associated with the exchange interaction between magnetic spin components also decreased with RE content increasing. The above results showed that the magnetic exchange interaction between magnetic atoms in gadolinium could be effectively changed by the Pr, Nd addition.
