Abstract:
1. A method comprising: forming a seed layer comprising a face-centered cubic (FCC) structure overlying a substrate; forming a dual-layer interlayer structure comprising a first interlayer and a second interlayer, wherein forming the first interlayer comprises forming a chromium alloy interlayer by sputter deposition in a gas atmosphere at a first pressure such that the first interlayer is overlying the seed layer, and wherein forming the second interlayer comprises forming the second interlayer by sputter deposition in a gas atmosphere at a second pressure greater than the first pressure such that the second interlayer overlies the chromium alloy interlayer; and wherein the second interlayer comprises a <0002> growth orientation; and forming a magnetic layer overlying the second interlayer.
