Spin-Electric Effect on a Chiral Dysprosium Complex
The Spin-Electric Effect (SEE) on molecules─the influence of external electric fields on molecular spin states─offers a compelling route toward low-power molecule-based spintronic applications. However, SEE remains elusive in molecular systems due to typically weak spin-electric field coupling. In this study, we observe a relevant SEE in a mononuclear lanthanide complex using Electric Field Modulated Electron Paramagnetic Resonance spectroscopy. We reveal a marked anisotropy of the SEE, evidencing that the most perturbed <i>g</i> tensor component is the one perpendicular to the electric field, providing hints for the most convenient experimental configuration to tune ad hoc spin transitions. <i>Ab initio</i> calculations in synergy with the experimental results revealed that molecular symmetry breaking plays a fundamental role. We also point out the crystal field parameters that are most strongly modulated by the presence of an electric field. These parameters are all off-diagonal, indicating effective electric-field-mediated state mixing.
