The effect of substitution of Ti for Co in compounds R{sub 2}Co{sub 17{minus}x}Ti{sub x} (R=Pr or Nd, and x=0.0{endash}2.0) on the structure and the magnetic properties has been investigated. It is found that the solubility of Ti in the compounds R{sub 2}Co{sub 17{minus}x}Ti{sub x} (R=Pr or Nd) is around 1.0. The R{sub 2}Co{sub 16}Ti (R=Pr or Nd) are isostructures to their parent compounds (rhombohedral), and its unit cell is expanded. The spontaneous magnetization {mu}{sub s} and Curie temperature T{sub C} decrease with increasing Ti content, owing to the magnetic dilution and the reduction of the moment of Co sublattice caused by Ti substitution. Moreover, an anomaly in the M-T curves of Pr{sub 2}Co{sub 16}Ti and Nd{sub 2}Co{sub 17{minus}x}Ti{sub x} compounds with x=0.5 and 1.0 may be attributed to a spin reorientation. This transition may originate from the change of crystal electron field due to the preferential occupation of Ti atoms on specific crystallographic sites. {copyright} {ital 1997 American Institute of Physics.}
