| 简介 | A magnetic stack includes a substrate and a magnetic recording layer disposed over the substrate. The magnetic recording layer comprises magnetic crystalline grains and a segregant disposed between grain boundaries of the crystalline grains. One or both of the magnetic crystalline grains and the segregant are doped with a rare earth or transition metal dopant in an amount that provides the magnetic recording layer with a magnetic damping value, α, between about 0.1 to about 1. | ||
