Abstract

We investigate hyperfine field (H_hf) distributions and electronic structures in magnetic Fe₅/Co₅ and Fe₅/Ni₅ multilayer systems using the standard Green function KKR band structure calculation. For the Fe₅/Ni₅ system the H_hf at the interfacial Fe site is about 10kG smaller than that at the interior Fe site, however, system the H_hf are almost constant in Fe layer for the Fe₅/Co₅. At the interfacial Ni site the H_hf is almost twice as large as at the interior Ni site or in bulk fcc Ni. Valence contributions to the hyperfine fields (H_v) play important roles for the H_hf distributions. We discuss the relations between core contribution and local spin moment and between valence contribution and total moment within the 1st and 2nd nearest neighbor shells.
