Abstract
Using time resolved neutron scattering, the evolution of the phase tra nsition between the paraelectric incommensurate (IC) phase and the fer roelectric commensurate (C) phase in Rb2ZnCl4 has been observed on a m icroscopic scale. The transformation was driven by a strong rapidly cy cling electric field of 8 kV/cm applied along the ferroelectric a-axis of the crystal. The response of the sample was monitored by measuring satellite reflections corresponding to the IC and the C phase, respec tively. Synchronization of the electric field to the time structure of the ISIS pulsed neutron source allowed us to observe field induced st ructural changes on a time scale of milliseconds. Characteristic relax ation times were found to depend strongly on temperature.
