  • Abstract
    We fabricated trilayer structures consisting of a Co-based full-Heusler alloy Co2Cr0.6Fe0.4Al (CCFA) layer, a Ru ultrathin film, and a Co90Fe10 layer, and demonstrated well-established antiferromagnetic coupling in the fabricated structures. Furthermore, we observed a clear exchange bias effect in a CCFA/Ru/Co90Fe10/IrMn layer structure with a typical exchange bias field of about 430 Oe at room temperature. These results indicate that the use of a CCFA thin film in antiferromagnetically coupled trilayers is advantageous for obtaining a strong exchange bias field
