| 简介 |
PURPOSE : Magnetic media and sputter targets with compositions of high anisotropy alloys and oxide compounds are provided to reduce the size of each magnetic domain on a storage layer of medium by using a high anisotropy constant as material.
CONSTITUTION : A magnetic media with compositions of high anisotropy alloys and oxide compounds comprises a magnetic storage layer(106) having a first alloy and oxide compounds having oxygen and more than one element. The first alloy has an anisotropy constant of at least 0.5x10^7 ergs/cm^3. The first alloy is also selected from a group consisting of L10-type ordered intermetallics, ordered HCP intermetallics, and rare earth transited metallics. The oxide compounds are deposited in an oxide-rich grain boundary isolating a magnetic grain boundary of the first alloy. The first alloy is selected from a group consisting of FePt, FePd CoPt, Mnal, Co3Pt, SmCo5, and Fe14Nd2B.
