We developed a [Co/Pt]n multilayer film for fabricating a perpendicular recording film with an ultrahigh coercivity (Hc). Adding boron into each Co layer and further introducing O2 during deposition yielded a high Hc of 1200 kA/m. Transmission electron microscopy and magnetic measurements suggested that the intergranular exchange coupling was reduced to the level of conventional CoCrPt-oxide granular films. The [CoB/Pt]n+O multilayer film is applicable to a hard magnetic layer in exchange-coupled composite media as well as energy-assisted magnetic recording media. [ABSTRACT FROM AUTHOR] |
