A reversible spin transition … … occurs when a single laser pulse (8 ns) is applied in the hysteresis loop (black curve) of the spin‐crossover complex [Fe(pyrazine){Pt(CN) 4 }] (structure shown). This bi‐directional, photoinduced spin switching occurs at room temperature over a wide region of bistability and involves magnetization as well as color changes (low spin: red; high spin: yellow). More details on this phenomenon are given in the Communication by A. Bousseksou and co‐workers on page 4069 ff.
