2 Nano-domain formation in LiTa03 single crystal 

In this study, we selected LiTa03 single crystal as a recording medium because this material has suitable characteristics as follows  

At the present time, two types of LiTa03 single crystals are widely known one is stoichiometric LiTa03 (slt) [20] and the other is congruent LiTa03 (clt). It is reported that domain inversion characteristics of these crystals are distinctly different each other [21-23], slt has
