The ferromagnetic after‐effect (MAE) was measured on high‐purity nickel samples (resistivity ratio R RT / R 4K > 2000) that had been irradiated with electrons (2.5 MeV) at 27 K with different doses and subjected to several annealing treatments. It was possible to separate the MAE from annealing effects taking place simultaneously. Taking into consideration annealing measurements of the MAE amplitude and the electrical resistivity published elsewhere, it is concluded that the 55 K‐MAE and the corresponding recovery stages I D , I E have to be attributed to the free diffusion of crowdions.
