Abstract

This paper presents results and an overview of magnetic and nanostructural properties of CoSm alloys which have high potential for future ultra high-density longitudinal magnetic recording. These sputtered films consist of about 5 nm crystallites embedded in an amorphous matrix, with the easy axes of the nanocrystallites in the film plane. The films have high coercivities, 3-4 kOe, and other highly favorable properties. Fundamental aspects of the relationship between nanostructure and magnetic properties are discussed.
