Abstract

We investigate the light induced optical hysteresis of spin-crossover compound driven by Gaussian noise. The stationary states was found from dynamic potential of noiseless system described in terms of Lyapunov functions. Cooperativity causes bistability of the steady state and provokes light-induced thermal and optical hysteresis. We study the influence of noise action on cooperative effects of photoexcited spin-crossover compound, leading to changes of system hysteresis. The stochastic dynamics of spin-crossover system was described following the Langevin formalism for noise driven system.
