Abstract

Density n_HS of photoexcited high-spin (HS) sites in a spin–crossover film (Nafion-[Fe(Htrz)₃]; Htrz = 1,2,4-4H-triazole) was systematically investigated against temperature T and excitation power density P. At low temperatures (≤35 K), the n_HS–P curve shows a nonlinear increase when P reaches a critical value (P_c). We interpreted the increase in terms of the dynamical phase transition into the condensed state of photoexcited HS molecules, and derived the P–T phase diagram. The P–T phase diagram and the n_HS–P curves were analyzed with an Ising-like model which includes a temperature-dependent field.
