Engineering exchange strength in S=1/2 molecule-based magnets

Abstract: Recent progress in the field of molecular magnetism has shown the potential for gaining control over the structural building blocks of molecular materials in order to engineer desirable magnetic properties. This was particularly evident in our recent work, where we showed that with small structural changes we could tune a system from a one-dimensional magnetic chain to an effectively zero-dimensional system which showed quantum spin-dimer behaviour. Our research has proved important in demonstrating how structure promotes and controls certain exchange pathways. Here we wish to investigate, in detail, how particular molecular ligands - pyrazine and 4,4' bipyridine - can be used to promote strong and weak exchange coupling. Specifically, we wish to study Cu(NO3)2(pyz)3 and [Cu(4,4’-bipy)(H2O)2(BF4)2].4,4’-bipy, which exploit new and different routes to realizing highly ideal model systems.
