Static domain structure of ferroelectric flux-grown KTiOPO4crystals

It is found that static domain structure in different growth pyramids and crystal cuts of flux-grown KTiOPO4 ferroelectric crystals can be visualized with high resolution and studied in detail by nematic liquid crystal method. The domain structure decorates the peculiarities of the crystal growth and corresponds, in the main, to the layers of growth. Head-to-head and tail-to-tail domain walls exist due to high ionic conductivity of the crystal in the region, of domain formation.
