A. Kirilyuk et al., ON THE BARKHAUSEN VOLUME IN ULTRATHIN MAGNETIC-FILMS WITH PERPENDICULAR ANISOTROPY, Journal of magnetism and magnetic materials, 159(1-2), 1996, pp. 27-32
Magnetic aftereffect studies as well as in-situ domain observation are
performed on gamma-Fe/Cu(001) films, providing the Barkhausen volume
values for these samples. On the basis of comparative STM studies we p
ropose the structural origin of the Barkhausen volume to be related to
the atomic terraces of the Cu(001) substrate.
