Magnetoelectric, Dielectric, and Optical Characteristics of Ferroelectric and Antiferroelectric Materials

Ferroelectric and antiferroelectric materials have attracted the attention of researchers in the last couple of decades due to their amazing applications such as magnetoelectric storage devices, positioners and generators, as well as magnetic field instruments. Ferroelectric and antiferroelectric materials display numerous kinds of physical attributes that include magnetoelectric, dielectric, and optical characteristics. The magnetoelectric impact describes interaction among electromagnetic fields in a material. In ferroelectric and antiferroelectric materials, this coupling may cause emergence of novel magnetic domains or alteration of operating domains as a result of an electric field being applied. These materials may additionally exhibit high dielectric constants, which make them useful in capacitive applications such as energy storage devices and high-frequency filters. Additionally, their optical properties, such as birefringence and nonlinear optical response, make them attractive for applications in electro-optic modulators and photonic devices. The behavior of ferroelectric and antiferroelectric materials is strongly influenced by the nature of their domain walls and defects, which can affect their magnetoelectric, dielectric, and optical properties. Understanding the mechanisms that govern these properties is crucial for the development of novel materials utilizing tailored characteristics for particular uses. In this chapter, we focused on the use of advanced characterization techniques, such as magnetoelectric, dielectric, and optical properties of ferroelectric and antiferroelectric materials. Continued research within this area is essential for the development of novel materials accompanying optimized characteristics for certain purposes in electronics, energy storage, and photonics applications.
