Abstract

Pb(Zrx,Til-x)O₃ (PZT) thin films (Zr/Ti=0.2/0.8) were deposited on the (001) SrTiO₃ single crystal substrates by PLD method. The ferroelectric-ferroelastic 90° domain structure formation process was examined in real time by in-situ heating TEM method. The 90° domain contrast weakened with heating, and disappeared about 470°C. The shape of the 90° domains were almost not changed till they have disappeared. In the 90° domain formation cooling process, the a-domain appeared at the same locus, in the same shape and configuration before the in-situ TEM experiment.
