摘要: A simple calculation of the RKKY coupling between two Gd arrays in a Gd‐Y superlattice is presented. The valid for consisting single atomic layer. Fourier transform J(q) exchange interaction layers separated by Y taken to be that embedded an matrix. Plausible arguments are given support this procedure. calculated making use only measured bulk and generalized susceptibilities Y. found fairly long range consistent sign with recent neutron scattering measurements long‐range order superlattices. Numerical calculations on model, one‐dimensional free‐electron metals different electron densities have not provided useful guide calculating interactions superlattices further theoretical work necessary.
