Theoretical studies of oscillatory behavior for long-range exchange bias

We have calculated the long-range exchange bias between a ferromagnet and an antiferromagnet separated by a nonmagnetic metal spacer. The RKKY interaction and dipolar interaction are used to analyze the temperature effects and thickness dependence in trilayer structure. The experimental observed osc...

Description
Summary:We have calculated the long-range exchange bias between a ferromagnet and an antiferromagnet separated by a nonmagnetic metal spacer. The RKKY interaction and dipolar interaction are used to analyze the temperature effects and thickness dependence in trilayer structure. The experimental observed oscillatory exchange bias through the metal spacer are in good agreement with the calculated results.
