Abstract

We here focus on the effect of a transition from metastable high-spin to stable low-spin states in spin-crossover compounds in contact with heat bath as external realistic (colored) noises. The systems are described by the way of stochastic methods using a phenomenological model of photoexcitation and relaxation in spin-crossover compounds. It is shown that such transitions can be controlled by a parameter that governs relaxation flow, intensity of light and noise intensity.
