We have studied the low-spin to high spin state phase transition induced by a single or a sequence of nanosecond laser pulses within the thermal hysteresis loop of the [Fe(NH<sub class="emphinferior">2</sub>-trz)<sub class="emphinferior">3</sub>](NO<sub class="emphinferior">3</sub>)<sub class="emphinferior">2</sub>-H<sub class="emphinferior">2</sub>O spin crossover compound. We demonstrate that the final state that is photoinduced can be finely controlled by changing the central wavelength and the energy of the laser pulses. A simple model accounts for the observed phenomena and paves the way for the practical applications to optical data storage at room temperature of spin state transition compounds.< Réduire
