Single-molecule magnets (SMMs) are promising molecular candidates for information storage and processing. However, properties like intra- and especially inter-molecular magnetic exchange interactions and how these affect the dynamic properties of SMMs are largely unexplored. SMMs are often linked by hydrogen bonds giving a path for magnetic exchange interactions. Hydrogen bonds are very susceptible to the hydrostatic pressure and we are currently demonstrating the dramatic dependence of an external pressure on the intermolecular exchange interactions by magnetic measurements. We wish to monitor the INS transition energies as a function of applied pressure, as these experiments will reveal more information on the nature of the intermolecular exchange. Comparison of the data obtained for the interlinked system and the isolated system unravels the effect of the external pressure on the isolated molecule itself. The low nuclearity of the SMM systems combined with the well-understood magnetic and spectroscopic properties of the suggested systems make them well-suited candidates for a fundamental understanding of mean field influence on the static and dynamic properties of SMMs.
