We investigate hyperfine field (Hhf) 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 Hhf at the interfacial Fe site is about 10kG smaller than that at the interior Fe site, however, system the Hhf are almost constant in Fe layer for the Fe5/Co5. At the interfacial Ni site the Hhf is almost twice as large as at the interior Ni site or in bulk fcc Ni. Valence contributions to the hyperfine fields (Hv) play important roles for the Hhf 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.
