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