摘要：
(Nd1-xSmx)(5)Fe-17 and (Nd1-xSmx)(5)(Fe1-yTiy)(17) samples were prepared by are melting and then annealed in vacuum. For the Nd-rich samples, Nd5Fe17 type structure was obtained by a long annealing (600 degrees C, 48 d); for the Sm-rich samples, it was obtained by a short annealing (750-900 degrees C, 1 d). With increasing Sm content, the easy magnetization direction converts from the basal plane to the c-axis. An easy-c-axis anisotropy is observed at room temperature for x greater than or equal to 0.3. A small amount of Ti favours the formation of Nd5Fe17 type structure only in the Sm-rich samples. It destroys this structure in the Nd-rich samples.
