Using Green function KKR band structure calculation method, hyperfine field distributions and electronic structures in Fe_3/Co_3 and Fe_3/Ni_3 multilayer systems are investigated where all the atoms are sited on regular or distorted bcc lattice points. In Co/[bccFe(100)] multilayer systems the calculated Co monolayer thickness d_<Co-Co> is almost equal to the value d_<[200]> of bcc lattice, and in Ni/[bccFe(100)] multilayer the Ni monolayer thickness d_<Ni-Ni> becomes smaller than d_<[200]> for bcc lattice. The calculated hyperfine fields at the Fe sites in the interior monolayers are enhanced and those at the Fe site in the interfacial monolayers are reduced from the values of bulk bcc Fe. It was found that the reduction of transferred hyperfine field (valence electron contribution to the hyperfine fields) results in the reduced hyperfine field at the Fe site in the interfacial monolayers.Multilayer SystemFeCoFeNiBand Structure CalculationHyperfine Field
