描述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 hav

Introduction,The present literature study is the result of a comprehensive literature analysis of United States, Japanese, British, French, German, European (Munich) and PCT (Geneva) patents, patent applications and other technical and scientific literature, published since January 1986.

Methods to Improve Other Properties and Characteristics of Magnets and Magnetic Materials,To make crystal grains fine, to increase the workability and to improve magnetic characteristics, Yoshitomo Sato (.) proposes a method comprising stirring an alloy, whose fundamental components are a rare earth element, iron and boron, in a semi-melting state of solid-liquid coexistence.

Methods to Lower the Production Costs of Magnets and Magnetic Materials,d for inserting and removing the tubes from the melt. The lower ends of the tubes are positioned well below the upper surface of the melt where the solid impurities collect. The molten alloy rises in the mold tubes to the selected level for forming the rods.
