The magnetic properties of La2Co17-x-yFexTiy and La2Co17-x-yFexTiyNδintermetallic compounds have been investigated. La2Co17-x-yFexTiy has the rhombohedral Th2Zn17 structure and exhibits magnetic properties as follows: saturation magnetization >1.0T, Curie temperature >873K and easy c-axis.
Nitrogen is introduced into these compounds interstitially through nitrogenation process. The saturation magnetization and Curie temperature of La2Co17-x-yFexTiyNδis decreased by introduction of nitrogen, on the contrary to Sm2Fe17.
