The photo-thermal effect of thermo-chromic crystals generates a novel kind of light-induced instability. We investigate here a mean-field (zero-dimensional) approach of the problem using basic equations of heat transfer and spin-crossover phenomena. This mean-field approach compares to the well-known Stoner-Wolfarth mechanism for the magnetization reversal of nano-particles, it should be suited to switchable micro-crystals and leads to auto-catalytic oscillations which remain to be observed. The stabilization of the high-spin–low-spin interface by photo-thermal effect is noticed.
