Induced V and reduced Fe moments at the interface of Fe/V(001) superlattices - art. no. 180407

Fe-n/V-m superlattices with n = 2,4 and m = 2,4,5 are studied by vibrating sample magnetometry and x-ray magnetic circular dichroism measurements. The combination of both techniques allows us to determine absolutely the induc ed V magnetic moment per atom. The samples with the thinnest V or Fe layers , respectively, reveal the largest induced moment of m(V) = 1.1 mu (B)/atom (Fe-4/V-2) and the strongest reduction of the Fe moment down to m(Fe) = 1. 34 mu (B)/atom (Fe-2/V-5). In addition, we probe the orbital magnetism of F e and discuss it with respect to previous results by ferromagnetic resonanc e and first principles calculations.
