Research Abstract

Spin-crossover (SC) complexes exhibit switching phenomena between the low-spin and high-spin states by change of external perturbations such as temperature, pressure, magnetic field, light-irradiation, etc. Elastic interactions caused by lattice distortions induce the phenomena and play a role of cooperative interactions. In this study we analyzed the properties of the interaction by building theoretical models of the elastic interaction. We showed that the elastic interaction induces an effective long-range interaction, and domain formation and nucleation dynamics in SC systems significantly depend on the shape of crystals. This feature is totally different from that of short-range interaction systems.
