Abstract

In this study, we have fabricated Heusler alloy Fe₂CrSi/Fe ₂VSi superlattice on MgAl₂O₄ substrate and have investigated inter-layer exchange coupling among Fe₂CrSi layers. Biquadratic coupling is dominated below the Neel temperature of Fe ₂VSi. By comparing magnetic coupling energy at 77 K and room temperature, it is suggested that the inter-layer exchange coupling is dominated by the proximity effect, i.e. the antiferromagnetic alignment of magnetic moments in Fe₂VSi spacer layer.
