Preface

The basic study and applications of magnetic materials have a long history. About a thousand years ago, the “South pointer,” a Chinese spoon made from a lodestone on a smooth plate, was an early magnetic device used for geolocation. However, there was little development of magnetic materials until the discovery of Faraday's law of electromagnetic induction. New hard and soft magnetic are emerging for electronic devices, communications, and information storage, and these are influencing our daily lives and modern industries. Especially with the development of quantum mechanics and electronics, theoretical study of magnetism has expanded in recent years and the research emphasis gradually has shifted from macroscale to nanoscale.

Nanotechnology is one of the most important developments in science and technology in recent years. Because matter behaves differently in the nanoworld, investigations of magnetic nanomaterials have brought revolutionary progress in materials processing and characterization. In contrast to bulk magnetic materials, magnetic nanomaterials have stimulated a series of novel theories, synthesis methods, and characterization techniques. In fact, although early researchers did not focus on the nanoscale, theoretical work revealed that nanoscale correlations exist in magnetic materials and control their properties. By virtue of their very nature, magnetic materials are a class of nanoscale materials. Some important concepts in magnetism, such as exchange coupling that controls magnetic domain thickness and the exchange length, have great influence on magnetic properties of nanomaterials. We have organized this book to systematically summarize our present knowledge of magnetic nanomaterials.

The book is structured into three parts – Fundamentals, Synthesis, and Applications – offering a broad introduction to magnetic nanomaterials. These three parts are divided into 16 chapters. Part One includes two chapters: Chapter 1 is an overview of nanomaterials, giving basic concepts and the time development of magnetic nanomaterials. Chapter 2 focuses on the magnetism of nanomaterials and demonstrates the differences between theories for bulk magnets and nanomagnets. Part Two includes eight chapters. Chapter 3 provides an overview of the synthesis of magnetic nanomaterials, including chemical and physical methods. Following this, Chapters 4–6 introduce the synthesis of soft magnetic nanomaterials, hard magnetic nanomaterials that consist of rare earth permanent nanocomposite magnets, and rare earth-free permanent nanocomposite magnets, respectively. The synthesis of magnetic chalcogenides is separately dealt with in Chapter 7. Because of their importance, Chapters 8–10 are devoted to wet-phase synthesis of typical magnetic nanoparticles with controlled morphologies and organized ensembles of magnetic. Part Three includes six chapters. At present, magnetic nanomaterials have notable advantages and potential in applications due to their increasing popularity and relevance for current applications and future prospects. Especially in biotechnology and biomedicine, magnetic nanomaterials can target a given cell or virus, provide accurate information on biological processes, and act as a multifunctional tool in cancer therapy. Chapters 11–13 introduce applications in biotechnology, diagnostics, and therapy mainly to present their superiority and distinguishing features. Applications of magnetic nanomaterials in data storage and electromagnetic wave absorption are covered in Chapters 14 and 15. Finally, Chapter 16 is about water remediation, which is a novel application. Magnetic nanomaterials show excellent performance in this field based on their magnetic recycling property.

In summary, this book attempts to exemplify emerging new materials, novel phenomena, and the most exciting developments in materials research and device applications. Discussions about reaction mechanisms and future prospects are also presented. We hope that this book will be a resource for future research in the related fields of magnetism and nanoscience.

We thank Dr. Peter Gregory, Dr. Gudrun Walter, and Dr. Lifen Yang from Wiley who initiated this book and did a great deal of work to bring it to completion. Ms. Nina Stadthaus worked diligently in collecting all the manuscripts, figures, and related paperwork. One of us (DJS) is grateful to the US Department of Energy, Office of Basic Energy Sciences, and the National Science Foundation for sustained research support. YH also thanks for the financial support of both National Natural Science Foundation of China and National Basic Research Program of China. Finally, we thank all of our authors who contributed their very informative and in-depth chapters that made this book a reality.
