The impact of number of repeats N on the interlayer exchange in $$[\text {Fe/MgO}]_{N} $$ [ Fe/MgO ] N (001) superlattices

Abstract The strength of the interlayer exchange coupling in [Fe/MgO] $$_N$$ N (001) superlattices with 2 ≤ N ≤ 10 depends on the number of bilayer repeats (N). The exchange coupling is antiferromagnetic for all the investigated thicknesses while being nine times larger in a sample with N = 4 as com...
