Abstract
The effects of the substitutions of Dy and Er for Sm on the crystal structure and magnetic properties of Sm2Fe17 and Sm2Fe17Ny compounds have been investigated. The structures of (Sm1-xR x )2 Fe17Ny compounds with R =Dy and Er and the hosts change from Th2Zn17-type to Th2Ni17-type with increasing Dy and Er contents. The replacement of Sm by Dy or Er results in a decrease in Curie temperature, saturation magnetization, and magnetic anisotropy field in the (Sm1-xR x )2Fe17Ny compounds. A tentative spin phase diagram of the (Sm1-xDyx)2Fe 17Ny compounds is suggested
