Spin-Electric Coupling in Molecular Magnets
arXiv:0805.1158 · doi:10.1103/PhysRevLett.101.217201
Abstract
We study the triangular antiferromagnet Cu 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.
