Low (10-150 keV He+, Ar+, and Kr+ ions) to intermediate (1-2 MeV He+, N+, and Au2+ ions) energy ion irradiation induced tuning of magnetic and structural properties of UHV electron-beam evaporated ultrathin Co/Pt and Co/Cr/Pt nanometer scale magnetic thin films on Si surfaces, over a localized area.

Correlated the changes in magnetic properties of the ion-irradiated bi- and mutli-layer thin films with those occurring in their structural properties.

Co-Pt and Co-Cr-Pt alloy systems are considered to be very important materials for high-density perpendicular magnetic recording (PMR) media. Therefore, these studies also indicate that depending upon ion energy, species, other implantation parameters, and even the area of the beam spot, one may be able to pattern such thin films towards their possible application in PMR media.
