The spin-crossover phenomenon in the solid state: Do domains play a role? A micro-Raman study

In order to assess experimentally the extent to which the nucleation-growth mechanism influences the phenomenon of spin-state crossover in the solid state, variable temperature micro-Raman mapping experiments have been conducted for the first time on the spin-crossover complex Fe(pz)[Ni(CN)4]·2H2O. The results point to the absence of domains with dimensions greater than ∼1 micron.
