摘要：

The polarization switching was studied in single crystals and thin films of 2-methylbenzimidazole (MBI) obtained by evaporation method from an MBI ethanol solution. Dielectric hysteresis loops were measured in the temperature interval 290-390 K and frequency range 20-1000 Hz for different amplitudes of the electric field. The Kolmogorov ss-model with account of Mertz law is used for simulation of hysteresis loops. The temperature dependence of domain wall motion activation field Ea has been obtained. Mechanisms of polarization switching in single crystals and films of MBI are discussed. In MBI films, a comparison of polarization switching for in-plane and out-of-plane electric field orientation is presented.
