摘要：

Using time-resolved neutron scattering, the evolution of the phase transition between the paraelectric incommensurate (IC) phase and the ferroelectric commensurate (C) phase in Rb2ZnCl4 has been observed on a microscopic scale. The transformation was driven by a strong rapidly cycling electric field of 8 kV/cm applied along the ferroelectric alpha-axis of the crystal. The response of the sample was monitored by measuring satellite reflections corresponding to the IC- and the C-phases. Synchronization of the electric field to the time structure of the ISIS pulsed neutron source allowed us to observe field-induced structural changes on a time scale of milliseconds. Characteristic relaxation times were found to depend strongly on temperature.
