Untangling the Magnetic Exchange Mechanisms in
Metal Organic Networks

The theoretical and experimental electron charge and spin density is measured and calculated in metal organic networks (based on S= or S=1 metal ions).
These studies enable full comprehension of the magnetic exchange mechanisms undergoing in these systems, where the magnetic network may or may not coincide with the structural network.

This work is carried out in the group of PD Dr. Piero Macchi.
