Rare Earth Permanent Magnets presents the discussion of the metallurgy and properties of rare earth permanent magnet alloys. The monograph initially provides the elementary aspects of magnetism to enable the reader sufficient understanding of permanent magnetism. The book then discusses the rare earth elements and their alloys with cobalt, copper, and iron; the magnetic properties of various intermetallic compounds relevant to permanent magnets; a detailed account of cast permanent magnets of the Co-Cu-Sm and Co-Cu-Ce systems and their modifications; the important methods of making and manufacturing rare earth permanent magnets by powder metallurgy methods; and comparisons between the well-known permanent magnets and the new rare earth materials. This text will be of value to students, materials engineers, and scientists.

These papers provide an interesting collection of contributions on fundamental magnetic behaviour, microstructural studies, processing methods and applications of rare earth, iron-rich, high performance permanent magnets. The remarkably versatile nature of the Nd-Fe-B-type alloys with respect to magnet processing is very evident in these proceedings. Thus there are papers which describe the production of magnets by the die-upset-forging of melt-spun ribbon, by cold-compaction of melt-spun-ribbon with soft metals, by mechanical alloying and by hot working of cast material. Work is also reported on the production of new permanent magnets from melt-spun material based on the alloys Nd4Fe78B18 and SmFe11.5Ti1.04. Both these alloys look promising and the former appears to be close to commercial exploitation.

The design advantages resulting from the linear demagnetization curves of rare-earth permanent magnets are discussed. The magnetic analogue to Ohm's law is derived and its affiliation illustrated by an example. Other aspects of design, such as the replacement of magnetic circuits with equivalent pole densities and the significance of the energy product, are also discussed. (Author) .

Rare-earth iron permanent magnets combine the magnetization of iron or cobalt with the anisotropy of a light rare-earth in intermetallic compounds which exhibit nearly ideal hysteresis. The rare-earth iron magnets are indispensable components in a vast range of electronic and electromechanical devices. This book covers the principles of permanent magnetism, magnet processing, and applications in a series of interlocking chapters written by experts in each area. Based on the findings of the Concerted European Action on Magnets, it is a definitive account of the field, designed to be read by physicists, materials scientists, and electrical engineers.

The present study complements the study on patents, patent applications and other literature on rare earth metals based permanent magnets by Frits Andriessen and Marten Terpstra, published by Elsevier Applied Science in 1989, and complements in part the book on Nd-Fe permanent magnets edited by LV. Mitchell, which was the result of a workshop organized by the Commission of the European Communities and held in Brussels on 25 October 1984. The difference between the content of the first book and that of the present study is that the first is more specifically directed to various kinds and compositions of alloys used in newly developed magnets, while the present book emphasises the improvements obtained when using particular alloys. The study edited by Mitchell deals more specifically with the economic, physical and chemical aspects of rare earth metals based magnet alloys, their properties compared with the more common and classical magnets such as ferro-cobalt alloy magnets, and their applications to various fields of technology. From the present study it has become apparent that there exist only a few patents and patent applications covering a specific use of particular magnets having specific properties to a circuit, arrangement, device or electric motor. This appears to be due to the fact that every manufacturer of such circuits or arrangements applying magnets naturally wants to employ the most effective magnets.
