THE FREEON THEORY OF MAGNETISM .2. MOLECULAR MAGNETS

摘要

In Article I, we showed that the freeon-exchange theory of magnetic coupling is a viable alternative to the widely used spin-exchange theory. In Article II, we are concerned with the symmetric-bridge, molecular magnet, AXB, where A and B are magnetic atoms and X is the bridge. The symmetric-bridge molecular magnet is of particular interest because the major features of its spectrum and its coupling constants are obtained by means of the two-electron, two-site freeon theory. We exhibit one example of ferromagnetic coupling, J > 0 and one of antiferromagnetic coupling, J < 0. (C) 1997 John Wiley & Sons, Inc. [References: 7]
