Název v původním jazyce

Possibility of using a PMN-PT single-crystal as a neutron optical device

Popis výsledku v původním jazyce

Variations of the Bragg diffraction angle induced by electric fields on piezoelectric single-crystal were investigated with the aim of exploiting such crystals as novel neutron devices. A (1-x)(Pb(Mg1/3Nb2/3)O3)-x(PbTiO3) (PMN-PT) single crystal with strong piezoelectric characteristics was used in the experiment. The sample was poled along <001> direction before the experiment. In the course of diffraction measurements, a 0.3° change was observed in the diffraction angle at the maximum induced by the electric field. The diffraction angle variation shows time dependent behavior, which can be well described using a single exponential decay limited to a saturated value. This effect is considered a result of a change of the domain structure brought aboutthrough long-term application of an electric field for several hours. The obtained preliminary results confirmed the possibility of using a piezoelectric crystal as a neutron optical device.
