After electron irradiation of cobalt single crystals a spectrum of magnetic after‐effect processes is observed where nearly all the relaxation peaks anneal out rapidly during the measurement. For the discussion of the experimental results a survey is given of the configurations of interstitial atoms and close Frenkel pairs which can be expected for the h.c.p. lattice. Taking into account resistivity annealing experiments the relaxation process at 325 K can be attributed to a diffusion after‐effect which is due to a freely migrating defect.
