Abstract
The magnetic after‐effect of deformed cobalt single crystals is investigated in the temperature region −120 to + 95 °C. Over the entire temperature region a weakly temperature‐dependent relaxation is found which obeys a logarithmic time law. Above room temperature another after‐effect is superimposed. This is interpreted as a diffusion aftereffect due to point defects. The annealing of the defects takes place at the same temperature, and obeys a first‐order rate equation. Methods of measurement are developed which take the annealing into account.
