| dc.description.abstractEn | Interplay between magnetism and electricity in multiferroic materials attracts growing theoretical and experimental interests. Indeed, these materials offer the possibility to control the magnetization without applying electric currents, opening the way for the development of new nanoscale memory elements with low power consumption. An inhomegeneous magnetization can induce an electric polarization in systems with broken inversion symmetry. Although this « flexomagnetoelectric » effect was theoritecally predicted more than twenty years ago [1], its unambiguous experimental evidence is still lacking. Here, we report direct evidence of the electric field induced by a magnetization inhomogeneity in an iron garnet film created by the non uniform magnetic fields generated at domain boundaries of a Type-I superconductor in the intermediate state. At liquid Helium temperatures, Stark shifts of sharp single molecule zero-phonon-lines were used to probe the local electric fields generated by this flexomagnetoelectric effect [2]. This observation paves the way to the use of ultra- sensitive nanometric probes such as single fluorescent molecules to directly investigate local electric fields in the condensed matter and to probe nanomechanical motions of charged oscillators. | |
