Abstract
A method to calculate the tunnelling state energy of mixed-valence clu sters using a secondary quantization technique has been developed. Thi s method makes it possible to obtain the analytical form for any matri x elements existing in double-exchange theory and to determine the mic rostructure of the parameters of this theory. The energy spectrum of t rimeric mixed-valence systems d(1)-d(1)-d(2) and d(4)-d(4)-d(5) are ca lculated, and the magnetic properties of these are investigated.
