Stochastic resonance in photo-switchable spin-crossover solids

The stochastic kinetic in photo-switchable spin-crossover materials with periodic driving force in the context of stochastic resonance (SR) was studied. The resonance phenomena in spin-crossover system have been analyzed by means of spectral power amplification (SPA) function. The influence of the parameters of harmonic signal (amplitude and frequency) together with changes of noise intensity have been considered. The SPA is characterized by double peak curve with qualitatively different mechanisms of amplification of the peaks and is examined by Fourier analysis.
