DOMAIN STRUCTURE EVOLUTION IN RELAXOR PLZT 8/65/35 CERAMICS AFTER CHEMICAL ETCHING AND ELECTRON BEAM IRRADIATION
Domains evolution on the surface of PLZT 8/65/35 ceramics after selective chemical etching and e-beam irradiation was studied. It is shown that the initial domains turned into lamellar domains as a result of such procedures. The observed etch-induced change of the domain structure was attributed to the action of the depolarization field after partial removing the screening charges. The dependence of the switched domain area on irradiation time (dose) was measured in e-beam irradiated samples.Π Π°Π±ΠΎΡΠ° Π²ΡΠΏΠΎΠ»Π½Π΅Π½Π° Ρ ΠΈΡΠΏΠΎΠ»ΡΠ·ΠΎΠ²Π°Π½ΠΈΠ΅ΠΌ ΠΎΠ±ΠΎΡΡΠ΄ΠΎΠ²Π°Π½ΠΈΡ Π£ΡΠ°Π»ΡΡΠΊΠΎΠ³ΠΎ ΡΠ΅Π½ΡΡΠ° ΠΊΠΎΠ»Π»Π΅ΠΊΡΠΈΠ²Π½ΠΎΠ³ΠΎ ΠΏΠΎΠ»ΡΠ·ΠΎΠ²Π°Π½ΠΈΡ Π£Π¦ΠΠ Β«Π‘ΠΎΠ²ΡΠ΅ΠΌΠ΅Π½Π½ΡΠ΅ Π½Π°Π½ΠΎΡΠ΅Ρ
