摘要：

The interaction, K(RM), between the rare earth 4f moment and the transition metal 3d moments in the series RFe2 (R = Gd-Yb) is shown to depend upon the R-5d moment, which is due to 3d-5d hybridization and local 4f-5d exchange integrals. K(RM) is calculated ab initio from density functional theory and is in excellent agreement with values extracted from inelastic neutron scattering experiments.
