This comprehensive textbook, aimed primarily at experimental chemists, physicists, electronic engineers, and material scientists interested in particulate and granular magnetic materials, represents the culmination of over 40 years of dedicated research in the field. The text is organized into two distinct parts. Part One delves into the fundamental physics of magnetism, commencing with an explanation of some peculiar terminology in magnetism, such as the concepts of poles and flux, which have origins that are not fully understood. The intricacies of the unit systems in magnetism are also presented. Subsequently, a brief review of domain theory is provided, followed by a detailed exploration of thermal activation effects and their accurate measurement. The topic of exchange bias, where an antiferromagnetic material is grown in intimate contact with a ferromagnet, is presented in great detail, encompassing a review of older theories and numerical models. However, the focus shifts to the York Model of Exchange Bias, which has emerged as the widely accepted model that describes the behavior of exchange bias systems when grown in the form of granular thin films.

Part Two of the textbook presents a comprehensive description of ferrofluids, encompassing a simple method for their preparation and a wide range of engineering applications in vacuum seals, loudspeakers, sink float separation, and the alignment of non-magnetic entities. Additionally, a detailed account of magnetic hyperthermia, a developing technology with significant potential applications in medicinal therapies, is provided. Other applications of magnetic nanoparticles in biomedicine are also discussed. An extensive discussion of magnetic information storage in conventional recording systems is presented, including a brief history of the development of this technology.

In conclusion, this textbook serves as a valuable resource for researchers and practitioners in the field of particulate and granular magnetic materials. It provides a comprehensive and up-to-date overview of the physics, applications, and emerging technologies related to these materials, making it an essential tool for advancing knowledge and innovation in this field.
