Publication number: 20080131735Abstract: The various embodiments of the present invention generally relate to the deposition of a seedlayer for a magnetic recording medium used for perpendicular magnetic recording (PMR) applications, where the seedlayer provides for grain size refinement and reduced lattice mis-fit for a subsequently deposited underlayer or granular magnetic layer, and where the seedlayer is deposited using a nickel (Ni) alloy based sputter target. The nickel (Ni) alloy can be binary (Ni—X; Ni—Y) or ternary (Ni—X—Y). In addition, the binary (Ni—X; Ni—Y) or ternary (Ni—X—Y) nickel (Ni) based alloys can be further alloyed with metal oxides, thus forming seedlayer thin films with a granular microstructure containing metallic grains, surrounded by an oxygen rich grain boundary. The nickel-based alloys (with or without metal oxides) of the various exemplary embodiments can be made by powder metallurgical technique or by melt-casting techniques, with or without thermo-mechanical working.Type: ApplicationFiled: December 5, 2006Publication date: June 5, 2008Applicant: Heraeus IncorporatedInventors: Anirban Das, Steven Roger Kennedy, Michael Gene Racine
