Abstract
The effect of irradiation on the movement of domain walls was studied in ferromagnetic transition metals by using a high voltage electron microscope. In iron, a domain wall became easily movable at a 300 kV irradiation. The mobility was less affected in cobalt, while in nickel the effect was the greatest.
