During the past 30 years materials science has developed into a full-fledged field for basic and applied scientific enquiry. Indeed, materials scientists have devoted their efforts to creating new materials with improved electronic, magnetic, thermal, mechanical, and optical properties. Often unnoticed, these new materials are rapidly invading our homes and automobiles, and may be found in our utensils, electronic equipment, textiles, home appliances, and electric motors. Even though they may go unnoticed, these new materials have either improved the efficiency and lifetime of these items or have reduced their weight or cost. In particular, magnetically ordered materials are useful in various applications, such as motors, magnetic imaging, magnetic recording, and magnetic levitation. Hence, much effort has been devoted to the development of better hard magnetic materials, magnetic thin films, and molecular magnets. During the same period of time, Mossbauer-effect spectroscopy has grown from a laboratory curiosity to a mature spectroscopic technique, a technique that probes solid-state materials at specific atomic sites and yields microscopic information on the magnetic and electronic properties of these materials. Iron-57 is the most commonly and easily used Mossbauer-effect isotope and, of course, is particularly relevant for the study of magnetic materials. Various applications of Mossbauer spectroscopy to magnetic materials are discussed in the first six chapters of this volume. Other isotopes such as zinc-67 and gadolinium-ISS have recently been used to study the electronic properties of zinc compounds and the electronic and magnetic properties of rare-earth transition metal compounds.

This book deals with many aspects of high density digital recording. It begins with very basic concepts in magnetism and magneto-optics, then continues with the synthesis and physical properties of recording media, thin films and particulate media. More technological aspects of recording heads and their contact with the recording media are also discussed in subsequent chapters. The second part of the book is devoted to the magneto-optical properties of various recording media and to the engineering of magneto-optical recording.

This volume covers in detail both the fundamental and practical properties of interstitial intermetallic materials, materials which are useful as hydrogen storage materials, as rechargeable hydrogen electrodes in batteries, and as new potential hard permanent magnetic materials. Various techniques, such as magnetic, diffraction, thermodynamic and spectral methods for studying these materials are covered in detail at a tutorial level. The synthetic methods used to obtain these new materials are also covered in detail. It combines the expertise from two different groups of scientists working on different properties and uses of several newly developed interstitial intermetallic materials. This includes scientists working on the thermodynamics of hydrogen storage materials and rechargeable hydride batteries and also those working on hard permanent magnetic materials. The two groups provide a different, but complementary, view of the properties of interstitial intermetallic materials. The book is intended for both scientists and engineers working in the field and advanced graduate students in the fields of chemistry, physics, materials science and materials engineering.
