Tīmeklis2016. gada 1. febr. · Our theoretical predictions are based on a combination of Landau-Khalatnikov-Tani approach (with a Ginzburg-Landau-Devonshire potential) to simulate the ferroelectric dynamics coupled to the magnetic dynamics. The latter is treated via the electric-polarization-dependent Landau-Lifshitz-Gilbert equation. Performing an … TīmeklisObserved hysteresis loops usually look much thinner and sloped than Landau-Khalatnikov ones [2], [7], [9], [24], [25], [26]. Also equations of Landau-Khalatnikov type describe homogeneous pyroelectric coefficient switching with the sharp peak near the thermodynamic coercive field value.
