Abstract: 
Based on multiscale calculations combining ab initio methods with spin dynamics simulations, we perform a detailed study of themagnetic behavior of Ni2MnAl/Fe bilayers.Our simulations showthat such a bilayer exhibits a small exchange bias effect when the Ni2MnAl Heusler alloy is in a disordered B2 phase. Additionally, we present an effective way to control the magnetic structure of the Ni2MnAl antiferromagnet, in the pseudo-ordered B2-I as well as the disordered B2 phases, via a spin-flop coupling to the Fe layer.
