Abstract. A study of dynamic of spin-crossover solid-state compound has been carried
out. The investigated macroscopic phenomenological model for molecular spin-crossover
complexes with optical control parameter has been extended to the case of noise action.
The noise-driven phase transition was observed. Also, ascertained was the role of
additive noise as a main factor for suppressing the potential barrier height.
Keywords: optical bistability, additive noise, multiplicative noise, noise-driven
dynamics.
