    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±ΠΎΡ‚Π° Π²Ρ‹ΠΏΠΎΠ»Π½Π΅Π½Π° с использованиСм оборудования Π£Ρ€Π°Π»ΡŒΡΠΊΠΎΠ³ΠΎ Ρ†Π΅Π½Ρ‚Ρ€Π° ΠΊΠΎΠ»Π»Π΅ΠΊΡ‚ΠΈΠ²Π½ΠΎΠ³ΠΎ пользования УЦКП Β«Π‘ΠΎΠ²Ρ€Π΅ΠΌΠ΅Π½Π½Ρ‹Π΅ Π½Π°Π½ΠΎΡ‚Π΅Ρ…Π½ΠΎΠ»ΠΎΠ³ΠΈΠΈΒ» Π˜Π•ΠΠΈΠœ Π£Ρ€Π€Π£ ΠΏΡ€ΠΈ финансовой ΠΏΠΎΠ΄Π΄Π΅Ρ€ΠΆΠΊΠ΅ Российского Ρ„ΠΎΠ½Π΄Π° Ρ„ΡƒΠ½Π΄Π°ΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½Ρ‹Ρ… исслСдований РЀЀИ (Π³Ρ€Π°Π½Ρ‚ 16-02-00821-Π°)
