Phys. Rev. Lett. 101, 217201 (2008) [4 pages]Spin-Electric Coupling in Molecular MagnetsReceived 8 May 2008; published 20 November 2008 We study the triangular antiferromagnet Cu3 in external electric fields, using symmetry group arguments and a Hubbard model approach. We identify a spin-electric coupling caused by an interplay between spin exchange, spin-orbit interaction, and the chirality of the underlying spin texture of the molecular magnet. This coupling allows for the electric control of the spin (qubit) states, e.g., by using an STM tip or a microwave cavity. We propose an experimental test for identifying molecular magnets exhibiting spin-electric effects. © 2008 The American Physical Society URL:
