Dual magnetic bistability with significant coercivity in a photo-responsive 1D Fe2Fe cyanide chain
Abstract
A cyanide-bridged 1D Fe2Fe chain exhibits rare dual magnetic bistability: thermal spin-crossover and light-induced single-chain magnet behaviour. Photoirradiation switches the system from a diamagnetic to a magnetically correlated paramagnetic state, featuring slow magnetic relaxation and a notably high coercive field of 0.52 T.
