Cooperative relaxation of the metastable states in the photomagnetic octacyanotungstate CsI[{CoII(3-CN-py)2}{WV(CN)8}] · H2O

Thanks to thermal quenching or irradiation, the metastable states of the photomagnetic CsI[{CoII(3-CN-py)2}{WV(CN)8}] · H2O compound have been studied by magnetic and reflectivity measurements. The thermodynamic parameters of the relaxation have been determined and used for the simulation of the magnetic properties in the thermal quenched state.
