Abstract High purity iron was irradiated at low temperatures with neutrons to various doses. Magnetic after‐effects due to radiation induced defects were investigated in careful annealing experiments from 4.5 to 300 °K. A number of pronounced orientation after‐effects with complex annealing behaviour were found. All relaxation amplitudes were roughly proportional to the dose. The after‐effects disappeared on annealing between 130 and 270 °K. A comparison with other experiments indicates that an annealing stage of the electrical resistivity or the stored energy may correspond to the annealing of several magnetic after‐effects.
