When subjected to external perturbation, ferroic materials exhibit unique behaviours such as electric polarization, magnetism, and strain. This book covers the basic science of ferroic materials, their mechanisms, applications, fundamental knowledge, and cutting-edge research. From ferroelectricity to ferromagnetism and multiferroics, this book explores how ferroic materials shape the future of electronic devices and smart technologies. The book discusses how such materials are developed to function as sensors, actuators, data storage, etc. Considering the theoretical background and state-of-the-art applications, this book is an essential resource for students, engineers, and researchers, providing a clear path to understanding the concepts and potentials of ferroic materials in day-to-day life.
