Foreword
Functional materials are of crucial importance in novel electronic
devices. Among functional materials, magnetoelectric multiferroics
represent a class of smart materials that transforms one basic
physical property into another. Magnetoelectric effect in these
materials is a product property of magnetostrictive and piezoelectric
components. There are many research papers on the magnetoelectric
interaction due to significant technological promises. The fact is that
composites have an obvious advantage over single-phase materials,
since they demonstrate a giant magnetoelectric response above
room temperature and are ready for technological applications. High
magnetoelectric coefficients necessary for engineering applications
can be achieved by the appropriate choice of components with high
magnetostriction and piezoelectricity. In this book, the authors
present their many years of experience in the study of magnetoelectric
composites and devices. The central issue explored by the authors of
this book is bringing together numerous contributions to modeling
of ME composites and the creation of prototypes based on them,
allowing one to consider magnetoelectric phenomena from a
new point of view based on their practical applications. It should
be noted that currently large number of works are devoted to the
study of the possibility of constructing the magnetoelectric devices,
which in a number of parameters should surpass the well-known
semiconductors, ferrite and ferroelectric ones. The authors have
examined several low-frequency and microwave magnetoelectric

devices and discussed the observed advantages in this book.
The focus of is on the advanced
modeling techniques and state-of-the-art experimental methods
that are essential to improve the magnetoelectric performance
of composites and devices. The book is useful for researchers and
