Influence of image forces on the electron transport in ferroelectric tunnel junctions
O. G. Udalov, I. S. Beloborodov
We study influence of image forces on conductance of ferroelectric tunnel junctions. We show that the influence of image forces is twofold: i) they enhance the electro-resistance e…
Competition of the Coulomb and hopping based exchange interactions in granular magnets
O. G. Udalov, I. S. Beloborodov
We study exchange coupling due to the interelectron Coulomb interaction between two ferromagnetic grains embedded into insulating matrix. This contribution to the exchange interact…
Competition of magneto-dipole, anisotropy and exchange interactions in composite multiferroics
A. M. Belemuk, O. G. Udalov, N. M. Chtchelkatchev +1
We study the competition of magneto-dipole, anisotropy and exchange interactions in composite three dimensional multiferroics. Using Monte Carlo simulations we show that magneto-di…
Phenomenological theory of magneto-electric coupling in granular multiferroics
O. G. Udalov, N. M. Chtchelkatchev, I. S. Beloborodov
We study coupling between the ferroelectric polarization and magnetization of granular ferromagnetic film using a phenomenological model of combined multiferroic system consisting…
Electron Transport Properties of Composite Ferroelectrics
O. G. Udalov, A. Glatz, I. S. Beloborodov
We study electron transport in composite ferroelectrics --- materials consisting of metallic grains embedded in a ferroelectric matrix. Due to its complex tunable morphology the th…
Interplay of charge and heat transport in a nano-junction in the out-of-equilibrium cotunneling regime
N. M. Chtchelkatchev, A. Glatz, I. S. Beloborodov
We study the charge transport and the heat transfer through a nano-junction composed of a small metallic grain weakly coupled to two metallic leads. We focus on the cotunneling reg…
