Exchange-mediated spin–electric control of single molecules on surfaces

Greule et al. demonstrated highly localized exchange-mediated spin-electric tuning and all-electrical coherent control of individual FePc and coupled Fe–FePc molecular spins using ESR-STM.

Key Results

• Observed nonlinear resonance shifts approaching $30\%$ near the FePc LUMO.
• Demonstrated voltage-controlled detuning of Rabi oscillations in single and coupled molecular-spin systems.
• Identified transport-mediated exchange bias from the magnetic STM tip as the dominant tuning mechanism.
