Abstract
An analytic solution for the Heisenberg Hamiltonian with long-range RKKY interactions on a Bethe lattice is obtained in the semi-classical approximation (S→∞). The main difficulty that has to be overcome is the exponential growth of the number of neighbors in a Bethe lattice. We suggest a way of handling this problem and derive physically meaningful results.
