Throughout the decades, semiconductors, metals and ceramics have been used in highly complex systems, viz., optical and magnetic mass storage media, sensors, therapeutics, light-emitting diodes, and optoelectronic devices.
In this regard, a large number of materials with modified and improved properties carry out various functions such as data collection, processing, transmission, storage and display information.
Technological advancements in magnetic and optical materials are shaping the boundaries shared by the various fields of physics, chemistry, engineering, medicine and materials science.
This book gives comprehensive information on the progress made in magnetic and optical materials. It also provides a few of the interesting features of these materials that have particular significance in their performance in various fields of science and technology.
Furthermore, this book is the sole compilation of important discussions about magnetic and optical materials such as their synthesis, properties, characterizations and applications in a single platform. The work included in this book has been organized into two parts.
The first part consists of magnetic materials. Different aspects of magnetic materials are discussed in detail by various authors in a way that should allow the scientific community to select the best materials for a particular application.
On the other hand, the second part consists of optical materials, providing past and most recent breakthrough discoveries in optics and photonics. This book is organized into fourteen chapters, the agendas of which are briefly described below.
Chapter 1 gives an introduction to the primary concepts of superconductivity, magnetism and their interaction in composite structures. It includes an overview of the structure and phase diagram as well as the properties of the superconducting and magnetic parts of these composites.
The magnetic anisotropy in different ferromagnetic materials is also reviewed. A survey of current experimental results is summarized, along with the theoretical calculations regarding different magnetic heterostructures.
In chapter 2, magnetic antiresonance in different metallic nanocomposites is reviewed in detail. The criterion needed for magnetic antiresonance to occur at frequencies of millimeter waveband along with the ferromagnetic resonance is also presented in a detailed manner.
Furthermore, the possible reasons for antiresonance existing in the reflection and absorption waves are discussed. Chapter 3 presents the recent development of glass ceramics with good bioactivity and magnetic property for bone healing and hyperthermia treatments of solid tumors.
In this chapter, various magnetic materials and their oxides doped with bioactive matrix and magnetic bioactive glass ceramic in different systems are investigated in detail.
Recent developments and various strategies in the preparation, microstructure, and magnetic properties of pure and surface functionalized iron oxide nanoparticles and their corresponding biological application are presented in chapter 4.
Also discussed are new functionalized strategies, problems and major challenges, along with current directions for the synthesis, surface functionalization and biomedical applications of iron oxide nanoparticles.
The direction and scope for further research in the area of functionalized iron oxide nanoparticles are also suggested. Further on, nanocarriers based on magnetic nanomaterials for anticancer therapy are presented in chapter 5.
This chapter reveals the great potential of magnetic nanomaterials for anticancer therapy by reporting and discussing promising examples of the published data.
The principles of anticancer therapy, as well as recent studies on magnetic nanomaterials for biomedical applications, are offered as a basis for understanding the mechanism of magnetic nanoparticle-mediated anticancer therapy.
A detailed theoretical study on the strain energy of carbon nanobelts, i.e., the belt-shaped molecules representing the sidewall structures of carbon nanotubes, is presented in chapter 6.
Chapter 7 gives an extensive overview of room-temperature molecular magnets modeling and applications based on metals and metal oxides. The mechanism by which moleculebased magnets stabilize and display a net magnetic moment is also given in this chapter.
