Magnetic domains are the elements of the microstructure of magnetic materials that link the basic physical properties of a material with its macroscopic properties and applications. The analysis of magnetization curves requires an understanding of the underlying domains. In recent years there has been a rising interest in domain analysis， probably due to the increasing perfection of materials and miniaturization of devices. In small samples， measurable domain effects can arise， which tend to average out in larger samples. This book is intended to serve as a reference for all those who are confronted with the fascinating world of magnetic domains. Naturally， domain pictures form an important part of this book. ^[2]
