    Four samples of Gd(Fe1−xCox)9Ti2 with x=0.0, 0.1, 0.2, and 0.3 were prepared by conventional arc melting followed by annealing at 1000 °C for 3 days. Powder‐x‐ray‐diffraction patterns of these samples show that all of the samples have a dominant phase with the tetragonal CeMn6Ni5 structure. Traces of TiFe2 are also present. 57 Fe Mössbauer spectra have been collected at 80 and 295 K. X‐ray‐diffraction patterns and Mössbauer spectra on magnetically aligned samples indicate that the easy axis of magnetization is the crystallographic c axis. The Curie temperature increases monotonically with increasing cobalt concentration. The average hyperfine field at 80 K reaches a maximum of 26.8(5) T for x≊0.2.
