    Computer simulations of sequency-dependent dielectric response of 90-degree domain walls in tetragonal barium titanate

  • Original language description

    Dissipation-limited motion of 90-degree domain walls in a defect-free BaTiO3 crystal under external electric field is investigated by computer simulations in the framework of Landau-Khalatnikov equation of motion and generalized Ginzburg-Landau-Devonshire model. Domain wall mobility determined directly from simulation of frequency dependent dielectric response is shown to be in a reasonable agreement with simple analytical estimates.

    Počítačové simulace frekvenčně závislé dielektrické odezvy 90-stupňových domenových hranic v tetragonálním BaTi03.

  • Czech description

    Pohyb 90-stupňových domenových hranic v ideálně čistém krystalu BaTi03 pod vlivem elektrického pole byl studován pomocí počítačové simulace v rámci Ginzburg-Landau-Devonshirova modelu s Landau-Khalatnikovou dynamikou. Pohyblivost hranic určená ze simulací je v rozumné shodě s jednoduchými analytickými odhady.
