摘要	The structure, magnetization, and magnetocrystalline anisotropy were investigated using X-ray diffraction, vibrating sample magnetometer, and AC susceptibility-meter. It is found that the mierostructure of (Sm0.5Nd0.5)(2)(Fe1-xCox)(17) alloys is an (Sm,Nd)(2)(Fe,Co)(17) phase with the rhombohedral Th2Zn17-type structure. The Curie temperature T, increases with the Co concentration increasing, and the magnetization first increases as the Co content increases in (Sm0.5Nd0.5)(2)(Fe1-xCox)(17) alloys and then decreases slowly. The easy magnetization direction (EMD) of (SM0.5Nd0.5)(2)(Fe0.25Co0.75)(17) is along the c-axis and a strong enhancement of the crystalline anisotropy energy constant K is produced by the addition of some Co atoms. The anisotropy energy constant reaches the maximum when x = 0.75 and then decreases slowly with the Co content further increasing. The (SM0.5Nd0.5)(2)(Fe0.25Co0.75)(17) compound is an optical candidate for the new permanent magnet, which possesses a high magnetization, a high Curie temperature, and a large anisotropy.
