Rezumat

A general solution of the double exchange problem is given for a mixed-valence system in which one migrating electron or hole is delocalized over an arbitrary number of transition metal ions (spin-core). A new efficient way for solving the magnetic vibronic problem is suggested based on the semiclassical approach.
