Abstract

This paper presents results on the growth and properties of nanocrystalline magnetic films with high anisotropy and thus relatively high coercivity. Such films have applications in several information technologies and this paper emphasizes future magnetic recording media at extremely high areal density (above about 10 giga bits per square inch). Elementary models of magnetization reversal, thermal stability, and noise are discussed, as well as measurements of activation volumes and derived magnetic cluster dimensions. Finally, recent measurements are discussed on novel nanostructured films with high potential for future high-density recording media.
