Magnetic properties and crystallography of double-layer CoCrTa thin films with various interlayers

In this work, the hysteretic properties and remanence curves of double-layer CoCrTa thin films with various interlayers (Al, Cu, Ag, and Cr) are investigated. It is found that the double-layer CoCrTa films with Cu or Ag interlayers have narrower switching field distributions but similar high coercivities, compared with the films with Cr interlayers. To understand the effects of interlayers on the magnetic properties, the crystallography of these multilayer thin films are studied. The results from this work show that Ag and Cu are strong candidates as interlayer materials in multilayer magnetic-recording media.<
