| 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. |
