Kinetic hysteresis in spin crossover solids analyzed using FORC diagrams

In this paper, we deal with the rate-dependent hysteresis in spin crossover complexes. The First-Order Reversal Curves (FORC) diagram method is proposed for characterizing the hysteretic behavior of the domain structure in spin transition compounds. In the present report we have completed the previous approaches, based on the Mean-Field Macroscopic Master Equation, by introducing the tunneling relaxation contributions.
