โœฆ Synopsis

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 anisotropy as a function of ion fluence allows to identify the step unbalance at the ion-sculpted surface as the origin of the magnetic anisotropy.

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 rip
