Enhanced antiferromagnetic coupling in dual-synthetic antiferromagnet with Co2FeAl electrodes

► Co2FeAl can be applied in room temperature dual-synthetic antiferromagnets. ► Co2FeAl dual-synthetic antiferromagnets have a good thermal stability up to 400 °C. ► The Co2FeAl has B2-ordered structure in annealed dual-synthetic antiferromagnets.
