ENCAPSULATED NANOMETER MAGNETIC PARTICLES |
摘要 |
Composite nanoparticles comprising an elemental metal core surrounded by a metal-containing shell material are described wherein the particles have an average diameter of from about 5-500 nm; the core metal is preferably selected from the group consisting of the transition metals and especially Fe, Co and Ni, whereas the shell material is advantageously a metal such as an alkaline earth metal, or a metal salt such as a metal oxide or metal halide. The shell material is preferably more oxophilic than the elemental core material, enabling the core metal to remain purely metallic. These core/shell composite particles can be used to fabricate magnetizable recording media such as tapes and disks. |
