Permanent Magnets in Automotive Applications

Applications of Permanent Magnets in Accelerators and Electron Storage Rings

After an explanation of the general circumstances in which the use of permanent magnets in accelerators are desirable, a number of specific magnets are discussed. This discussion includes magnets needed for the opera tion of accelerators as well as magnets that are employed for the utilization of charged particle beams, such as the production of synchrotron radiation. Generic Advantages of Perm...

Rare-earth Permanent Magnets: New Magnet Materials and Applications

The introduction of rare-earth permanent magnets based on samarium-cobalt in about 1970, and neodymium-iron-boron magnets in the mid-nineteen eighties, has ushered in a new era in hard magnetic materials. This has resulted in a dramatic improvement in permanent magnet performance, with neodymium-iron-boron (Nd2Fe14B) magnets having a magnetic energy product up to an order of magnitude greater t...

Advances in nanostructured permanent magnets research

This paper reviews recent developments in research in nanostructured permanent magnets (hard magnetic materials) with emphasis on bottom-up approaches to fabrication of hard/soft nanocomposite bulk magnets. Theoretical and experimental findings on the effects of soft phase and interface conditions on interphase exchange interactions are given. Synthesis techniques for hard magnetic nanoparticle...
