Method of producing exchange coupled magnetic thin films with post-deposition annealing |
摘要 |
Exchange coupled magnetic thin films are produced by depositing an antiferromagnetic layer, followed by deposition of a layer of ferromagnetic material on the antiferromagnetic layer. The composite antiferromagnetic/ferromagnetic structure is then annealed at an elevated temperature for a predetermined length of time. This process results in considerably higher exchange coupling fields than obtainable before. Alternatively, the antiferromagnetic layer may be annealed prior to deposition of the ferromagnetic layer.
