Underlying mechanism for exchange bias in single-molecule magnetic junctions

Magnetic proximity has been observed in a variety of solid-state magnetic devices, but less discussed at the molecular scale. In this study, magnetotransport calculation is carried out using generalized Landau-Lifshitz-Gilbert (LLG) equation combined with density functional theory (DFT) and our self-developed junpy calculated spin-torque effect. Except for current driven spin torque, which promising approach magnetization switch random access memory, equilibrium fieldlike torque also plays crucial role strain-controlled exchange bias current-controlled coercivity single-molecule junctions. The tight-binding model further employed to clarify critical interfacial filter effect arising from hybridization between linker Co apex. These multidisciplinary DFT+junpy+LLG results may provide important practical implications dual control switching spintronics low temperature, either by tensile strain or via smaller applied order $\mathrm{MA}/{\mathrm{cm}}^{2}$.
