Our theoretical physicists demonstrated “electrical control of spin currents in graphene via ferroelectric switching”

European research team led by RNDr. Martin Gmitra, Phd. has theoretically proposed a new approach to controlling spin currents in graphene by its coupling with a ferroelectric monolayer of In₂Se₃. Using first-principles calculations and simulations of strong coupling, the researchers demonstrated that ferroelectric switching in In₂Se₃ can reverse the direction of the spin current in graphene, effectively acting as an electric spin switch. This discovery opens a new pathway for energy-efficient spintronic devices without the need for a magnetic field, representing a key step toward next generation logic and memory systems based on spin-controlled spin textures. The research results will be published in the Materials Futures journal.
