In ferromagnetic b.c.c. FeTi alloys (2at%, 10at%Ti) the magnetic relaxation spectrum of diatomic TiH and TiD complexes is studied in the temperature range from 10 to 180 K. The relaxation spectra of both the types of complexes are composed of two overlapping relaxation maxima which may be attributed to different relaxation modes of the diatomic complexes. A significant isotope effect can be detected for the activation energies whereas in the case of the pre‐exponential factors no significant isotope effect can be observed.
