我们制作的三层结构组成的钴基全Heusler合金Co2Cr0.6Fe0.4Al（CCFA）层，钌的薄膜，和Co 90 Fe 10层，并证明了良好建立的反铁磁耦合在制造的结构。此外，我们观察到一个明确的CCFA/Ru/Co 90 Fe 10/IrMn层结构中的交换偏置效应，在室温下的典型交换偏置场约为430 Oe。这些结果表明，在反铁磁耦合三层膜中使用CCFA薄膜有利于获得强交换偏置场
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
