Abstract

Undoped and 5mol%MgO DOPED {{{{ { LiNbO}_{ 3} }}}} were grown by floating zone method. The grown crystals were poled to c-azis in different electric conditions. Ferroelectric domain patterns related to the poling conditions were investigated by chemical etching and the poling effects on the piezoelectric in the undoped and MgO doped Crystals were studied.
