High-Nuclearity Mixed-Valence Magnetic Clusters - A General-Solution of the Double Exchange Problem

Borrasalmenar JJ, Clemente JM, Coronado E, Palii AV, Tsukerblat BS, Georges R

We report here a general solution of the double-exchange problem in the high-nuclearity mixed valence systems containing arbitrary number P of the electrons delocalized over the network of N (P
