In this work, the effects of Pr content on the structure and intrinsic magnetic properties of Sm_(1-x)Pr_xCo_5(x = 0–0.6) compounds prepared by induction melting were systematically investigated by scanning electron microscopy(SEM), X-ray diffraction(XRD), and magnetic measurements. Microstructural observation and chemical composition analysis show that Sm_(1-x)Pr_xCo_5 compounds are composed of(Sm, Pr)Co(1:5) phase and(Sm, Pr)-rich grain boundary phase. XRD results show that all the Sm_(1-x)Pr_xCo_5 compounds have a(Sm, Pr)_1Co_5 main phase with the hexagonal CaCu_5-type crystal structure and the(Sm, Pr)_2Co_7 impurity phase. In addition, the detailed research shows that the lattice constants(a, c) and unit volume(V) are all enlarged with the increases in Pr content. According to the magnetic measurements, as the Pr content increases to larger than 0.4, both the Curie temperature(T_C) and the anisotropy field(H_A) of all the Prdoped compounds decrease rapidly. Meanwhile, the magnetization of Sm_(1-x)Pr_xCo_5 compounds at applied field of 14 T(M_(14 T)) are observably improved with Pr doping content of x>0.3. Among them, Sm_(0.6)Pr_(0.4)Co_5 compound exhibits slightly lower H_Aand T_C, but much higher M_(14 T) than those of the binary SmCo_5, indicating that doping of proper Pr content into SmCo_5 compound can optimize the intrinsic magnetic properties. As a result, the optimal intrinsic magnetic properties of H_A= 29.11 T,T_C= 989 K, and M_(14 T)= 102.31 mA·m~2·g-1are obtained in Sm_(0.6)Pr_(0.4)Co_5 compound.
