Room-Temperature Electrical Addressing of a Bistable Spin-Crossover Molecular System

A switchable molecular device is constructed by contacting an individual nanoparticle based on spin-crossover molecules between nanometer-spaced electrodes. The switching and memory effects near room temperature are a consequence of the intrinsic bistability of the nanoparticle. Interestingly, for molecular spintronics, the spin crossover can also be induced by applying a voltage, showing that its magnetic state is electrically controllable.
