Strong Exchange Couplings Drastically Slow Down Magnetization Relaxation in an Air‐Stable Cobalt (II)‐Radical Single‐Molecule Magnet (SMM)
Abstract: The energy barrier leading to magnetic bistability in molecular clusters is determined by the magnetic anisotropy of the cluster constituents. By incorporating a highly anisotropic four‐coordinate cobalt (II) building block into a strongly coupled fully air‐ and moisture‐stable three‐spin system, it proved possible to suppress under‐barrier Raman processes leading to 350‐fold increase of magnetization relaxation time and pronounced hysteresis. Relaxation times of up to 9 hours at low temperatures were found.
