In the local spin density approximation to the density functional theory the interaction, K(RM), between the rare-earth 4f moment and the transition metal 3d moments in rare earth-transition metal intermetallics is shown to depend on the R-5d moment and local 4f-5d exchange integrals. Detailed examples are given for the RFe(2) (R = Gd - Yb) series. The calculated local exchange integrals are shown to be energy dependent and are then related to the molecular fields.
