Abstract. Considering the time-delayed feedback and environmental perturbations in spin-crossover system,
we construct a stochastic delayed differential equation to study the state transitions from the low
spin (LS) state to the high spin (HS) state in spin-crossover solids. It is shown that the delayed feedback
and noise can induce optical bistability and state transitions. The mean first-passage time (MFPT) of the
transition from the LS state to the HS state as the function of the noise intensity exhibits a maximum,
and the noise-enhanced stability is observed. However the MFPT decreases with increase of the delayed
feedback intensity, thus the delayed feedback accelerates the conversion from the LS state to the HS state.
