“…The piezoelectric strains are not transferred to the magnetic inclusion via the pore such that the strain-induced coupling is impeded and the ME coefficient is reduced. An additional influence is shown in Figure 1(right) by different ferroelectric pre-polarization states, which vary the piezoelectric properties of the matrix material and consequently the ME-coupling coefficient α 33 [9].…”

Magneto‐electric (ME) composite materials enable a coupling between magnetization and electric polarization. This magneto‐electric coupling finds application in sensor technology and data storage devices. Since this coupling is a strain‐induced product property which arises due to the interaction of the different phases, suitable material models for the individual phases as well as microscopic defects, such as pores, have to be considered for precise numerical simulations. In this contribution we implemented suitable material models for both phases describing the behavior on the microscopic level and considered pores which influence the overall ME response. In order to determine the effective properties a two‐scale finite element (FE2) homogenization approach is performed. The remanent magnetization behavior is described using a Preisach operator whereas the remanent electric polarization arises due to a ferroelectric/‐elastic switching criterion based on a change in the free energy.

The Preisach model is a well-known model of hysteresis in the modern nonlinear science. This paper provides an overview of works that are focusing on the study of dynamical systems from various areas (physics, economics, biology), where the Preisach model plays a key role in the formalization of hysteresis dependencies. Here we describe the input-output relations of the classical Preisach operator, its basic properties, methods of constructing the output using the demagnetization function formalism, a generalization of the classical Preisach operator for the case of vector input-output relations. Various generalizations of the model are described here in relation to systems containing ferromagnetic and ferroelectric materials. The main attention we pay to experimental works, where the Preisach model has been used for analytic description of the experimentally observed results. Also, we describe a wide range of the technical applications of the Preisach model in such fields as energy storage devices, systems under piezoelectric effect, models of systems with long-term memory. The properties of the Preisach operator in terms of reaction to stochastic external impacts are described and a generalization of the model for the case of the stochastic threshold numbers of its elementary components is given.
