摘要：

A method for calculating the energies of the tunnel states of mixed-valence clusters is proposed. It is based on the secondary quantization technique and allows one to obtain analytical expressions for all matrix elements that appear in double exchange theory as well as to determine the microstructures of the parameters of this theory. The energy spectra of trimeric systems are calculated with allowance made for the three-center transfer integrals, and Me magnetic properties of these systems are investigated.
