dc.description.abstractEnThe spin-crossover phenomenon is a cooperative low-spin to high-spin transition which can be initiated using temperature or light-irradiation. We have used muon-spin relaxation (μSR) to study this effect in Fe(PM-PEA)2(NCS)2 and Fe(PMAzA)2(NCS)2. We find Gaussian or exponential muon relaxation in the high-spin phase for the two compounds, reflecting differences in their intermolecular interactions. For both compounds, the low-spin phase gives rise to root-exponential relaxation which we associate with a dilute distribution of fluctuating moments resulting from incomplete spin crossover.
