✦ Synopsis

The possibility of modifying the magnetic properties of ultrathin films by means of ion sculpting has been verified for Co/Cu(0 0 1) and Fe/Ag(0 0 1). For both these systems, ion sputtering at grazing incidence performed in a proper, material-dependent, temperature range induces the formation of ripples at the surface of the films. Following ripple formation, the magnetic anisotropy in the plane of the films undergoes dramatic changes brought about by the out-of-equilibrium distribution of defect sites induced by the ripple structure itself.

The onset of in-plane uniaxial magnetic anisotropy in ion-sculpted ultrathin Fe/Ag(0 0 1) films has been investigated. Uniaxial anisotropy already develops at ion fluences where the self-organisation of the ripple structure has not yet started. The evolution of the strength of the uniaxial anisotrop
