%X nd16co72-xruxc11b boro-carbides have been prepared by arc melting and studied by x-ray diffraction and magnetization measurements. x-ray diffraction results confirm that all the prepared alloys possess the tetragonal 2:14:1 (p42/mmm) hard magnetic phase. the observed decrease of the magnetization and curie temperature indicate the development of antiferromagnetic spin correlations with the increase of the ru content. the combined addition of b and c is favorable to the formation and stabilization of the tetragonal phase in these compounds. at lower ru contents the curie temperature is higher than in the corresponding co-based boride in spite of larger cell volumes.
