Abstract
Due to the collective behaviour of their magnetic excitations, arrays of coupled S = 1/2 spin dimers, exposed to a magnetic field, are of general interest in solid state physics as they can be considered as the source for generating a gas of interacting bosons. We present a new class of coupled spin-dimer systems based on purely organic building blocks. From magnetic susceptibility and magnetization data of various nitronyl-nitroxide biradicals, we extract the influence of the bridging ligands on the intra-dimer coupling constant Jdimer. The target materials show moderate values of Jdimer ranging from 5 to 10 K, and indications for significant inter-dimer couplings. The moderate size of these couplings, together with the high flexibility against chemical modifications, make these materials promising candidates for studying interacting quantum objects under well-controlled conditions.
