Calorimetric measurements of the light-induced metastable high-spin state on the [Fe(PM-BiA)2(NCS)2] complex

For the first time, the heat capacity of the LIESST photo-induced state has been measured. Heat capacity measurements have been obtained with AC calorimetry on a pellet sample of [Fe(PM-BiA)2(NCS)2] formed by applying uniaxial pressure on the powder compound.
