A Light‐Induced Phase Exhibiting Slow Magnetic Relaxation in a Cyanide‐Bridged [Fe₄Co₂] Complex

Abstract

Single-molecule magnets: A cyanide-bridged hexanuclear complex showed a thermal electron-transfer-coupled spin transition centered at 220 K. Light irradiation at low temperature (LT; HT = high temperature) generated a metastable state showing slow magnetic relaxation in measurements of the alternating-current magnetic susceptibility (χ(m); see picture).
