When presented with a new compound or material, the inorganic chemist will usually have several questions in mind about its composition and structure. Although a simple elemental analysis may answer many questions about its composition, the chemist will still have questions about its structure, and, ifthe material contains a metal atom, he will often want to know its oxidation state, coordination number and geometry. Further, at an increasingly frequent rate, the chemist may need details of the spin- state, magnetic and perhaps dynamic properties of the material. If the investigator is...

Volume 2 presents the latest applications of M ssbauer spectroscopy to the study of magnetic materials. Topics include: Surface and thin film analysis, iron-based amorphous ribbons and wires, diffusion studies, analytical methods for M ssbauer spectral analysis of complex materials, and quasicrystalline materials among others. These discussions will be invaluable to materials scientists, inorganic chemists, and solid-state chemists.

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...

This book represents Volume 2 in a series on the use of Mossbauer spectroscopy in the study of magnetism and materials. However, the perceptive reader will notice some differences from Volume 1. Specifically, in order to market the book at a more affordable price for most universities and research laboratories, the book has been prepared in camera- ready format The editors and the authors agreed to do this because there is a demand for such a book in the Mossbauer community. This format has placed an extra burden on the editors and the authors and we hope we have overcome all the difficulties...

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.

The book you are now holding represents the final step in a long process for the editors and organizers of the Advanced Study Institute on hard magnetic materials. The editors interest in hard magnetic materials began in 1985 with an attempt to better understand the moments associated with the different iron sites in Nd Fe B. These 14 moments can be obtained from neutron diffraction studies, but we qUickly realized that iron-57 Mossbauer spectroscopy should lead to a better determination of these moments. However, it was also realized that the complex Mossbauer spectra obtained for these hard...

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.

As is often the case, the preface is the last task to be finished during the preparation of a large volume such as you are now holding. The first task, obtaining approval for a symposium on the industrial applications, now seems a long time ago. The idea orginated with John Stevens, probably in 1982, from his observation of papers dealing with industrial applications of the Mossbauer effect appearing in the Mossbauer Effect Reference and Data Journal. His initial suggestion for a symposium entitled "Industrial Applications of the Mossbauer Effect" to be held at a national meeting of the...

In 1988 the Mossbauer effect community completed 30 years of continual contribution to the fields of nuclear physics, solid state science, and a variety of related disciplines. To celebrate this anniversary, Professor Gonser of the Universitat des Saarlandes has contributed a chapter to this volume on the history of the effect. Although Mossbauer spectroscopy has reached its mature years, the chapters in this volume illustrate that it is still a dynamic field of science with applications to topics ranging from permanent magnets to biologi- cal mineralization. During the discussion of a...
