Nano-patterning of Co/Pt multilayers.

PDF Version Also Available for Download.

Description

One of the most promising new systems for both basic research and technical development are the periodic arrays of nano-magnetic elements, as shown. Such arrays show remarkably rich and novel magnetic behavior. Periodic magnetic arrays not only provide excellent opportunities for new science but also constitute a promising candidate for new applications such as high-density, patterned magnetic memory for advanced computer designs in the next decade. In the presentation they will focus on patterned [Co4 {angstrom}/Pt10 {angstrom}]n multilayers, which demonstrate an unusually strong out-of-plane magnetic anisotropy and sensitivity to structural modification. This strong out-of-plane anisotropy makes Co/Pt ML the favorite ... continued below

Description

One of the most promising new systems for both basic research and technical development are the periodic arrays of nano-magnetic elements, as shown. Such arrays show remarkably rich and novel magnetic behavior. Periodic magnetic arrays not only provide excellent opportunities for new science but also constitute a promising candidate for new applications such as high-density, patterned magnetic memory for advanced computer designs in the next decade. In the presentation they will focus on patterned [Co4 {angstrom}/Pt10 {angstrom}]n multilayers, which demonstrate an unusually strong out-of-plane magnetic anisotropy and sensitivity to structural modification. This strong out-of-plane anisotropy makes Co/Pt ML the favorite candidates for perpendicular magnetic recording. The patterned Co/Pt ML are representatives of a new generation of magnetic nanostructures with lateral dimensions in 100 nm range, and individual layer thickness approaching a monolayer scale (e.g., 4 {angstrom} of Co and 10 {angstrom} of Pt). In addition to traditional lithography, they are developing a new approach to tailoring the local magnetic properties of Co/Pt ML. In this process the local magnetic properties are modified not through conventional modulation of the chemical composition, but through structural modification induced by low energy ion implantation.
