This book explores ferroic crystals, focusing on the intricate relationship between their macroscopic properties and microscopic phenomena. Ferroic materials, characterized by hysteresis cycles that link magnetization, polarization, and deformation to their respective fields, are pivotal in understanding and advancing various technological applications.

For the first time, this volume presents experimental evidence directly linking macroscopic responses to microscopic interface phenomena—domains, domain walls, and phase fronts—offering unprecedented clarity into the inner workings of ferroic systems. Simultaneous observations of domains, susceptibility measurements, and gamma diffractometry reveal how these microscopic structures govern the shape and coercive fields of hysteresis cycles, especially at first-order phase transitions.

The book bridges the gap between macroscopic measurements and nanoscopic insights, highlighting how domain interactions influence susceptibility through both short- and long-range effects, including freezing processes, isolated walls, and events occurring within the walls themselves. It further demonstrates how domain wall interactions—often overlooked in theoretical models—play a critical role in the reversal of ferroic order parameters.

Special attention is given to the interplay between ferroelasticity and ferroelectricity, delving into energy dynamics, phase transitions, and thermodynamic models. Notably, the manipulation of chemical, mechanical, and electrostatic energies in first-order transitions is shown to affect the shape of phase fronts, which may appear as planes, “factory roof” geometries, or even fractal patterns, and may include periodic inclusions of one phase in another.

With clear explanations, visual demonstrations, and practical experimental insights, the book caters to researchers and students aiming to deepen their understanding of these phenomena. Designed for both seasoned scientists and budding researchers, it integrates experimental data, simulation results, and theoretical models to provide a holistic understanding of ferroic crystals, their behaviors, and their applications in modern science and technology.

Über Autor(innen)

Professor of the Joseph Fourier University (Honorary Professor of the Grenoble Alps University), Jean Bornarel was one of the first to understand ferro-elasticity existence at a time when only ferroelectricity was known. His activities in different fields persuaded him that it was necessary to propose bridges between them. In this book, bonds between ferroelectrics and ferro-elastics on the one hand and between nano, micro and macro levels on the other.
