概要

• 論文の詳細を見る

• We have performed in situ synchrotron-radiation X-ray powder structural analysis in a spin-crossover complex ([Fe(ptz)_6)](BF_4)_2: ptz = propyltetrazole) under a photo-excitation with a continuous-wave (CW) green (532 nm) laser at 91 K. The Fe^2+ ions in the Fe(ptz)_6 molecules take the low-spin (LS:S = 0) state at the ground state, and are photo-excited selectively into the high-spin (HS: S = 2) state. When the excitation power P exceeds the critical value, we observed a novel secondary phase which can be ascribed to the condensation of the photo-excited HS ions.
