Existence of Finitely Many Solution Branches and Nested Hysteresis Loops in Ferroelectric Materials
نویسنده
چکیده
We consider Ginzburg-Landau energy for ferroelectric materials so as to study their structures during the polarization reversal process by an externally applied electric field. We accomplish very useful mathematical results which connect this problem with other situations in material sciences. Taking into account the Neumann boundary condition, we obtain inhomogeneous solutions and study hysteresis effects in the relation between polarization and applied field, which characterizes the ferroelectric phenomenon.

Modeling saturated and unsaturated ferroelectric hysteresis loops: An analytical approach
In ferroelectric materials, hysteresis behavior is very difficult to model due to its nonlinear and history-dependent characteristics. Among approaches that are able to describe unsaturated loops, many of them are either very complicated numerical procedures must be employed or the resulting loops contain some undesirable or defective features. In this work, a simple hysteresis model based on a...
متن کاملBiasing Effects in Ferroic Materials
In this chapter we present an overview of some important concepts related to the processes and microstructural mechanisms that produce the deformation of hysteresis loops and the loss of their symmetry characteristics in ferroelectric, ferroelastic and ferromagnetic systems. The most discussed themes include: aging and fatigue as primary mechanisms of biased hysteresis loops in ferroelectric/fe...

متن کاملModeling and Analytical Study for Ferroelectric Materials
We discuss rate-independent engineering models for multi-dimensional behavior of ferroelectric materials. These models capture the non-linear and hysteretic behavior of such materials. We show that these models can be formulated in an energetic framework which is based on the elastic and the electric displacements as reversible variables and interior, irreversible variables like the remanent po...
متن کاملMonte Carlo Simulation of Ferroelectric Domain Structure: Electrostatic and Elastic Strain Energy Contributions
A lattice-Monte Carlo approach was developed to simulate ferroelectric domain behavior. The model utilizes a Hamiltonian for the total energy that includes electrostatic terms (involving dipole-dipole interactions, local polarization gradients, and applied electric field), and elastic strain energy. The contributions of these energy components to the domain structure and to the overall applied ...
