ABSTRACT:
Perpendicular magnetic media are described for use in magnetic recording and data storage. Seed layer compositions are described which can facilitate perpendicular magnetic anisotropy in subsequently deposited magnetic layers. In particular, nickel-iron-chromium (NiFeCr) alloys or nickle-chromium (NiCr) alloys can be used as seed layers which cause a subsequently multi-layered magnetic stack to assume perpendicular magnetic anisotropy. In this manner, high perpendicular magnetic anisotropy can be achieved and storage densities of media may be increased.
