Bonded magnets are the fastest growing sector in the entire market for magnetic materials. Their great advantages lie in the cost effective net-shape manufacturing process allowing the achievement of complex geometries and their isotropic magnetic properties. Energy products have more than quadrupled in recent years, too. The contributors to this volume present the current and future status of bonded magnets, including total world production and distribution, the markets involved, and the status of current and future applications. Current novel processing techniques are described and new developments reported, including powder production techniques, jet casting/melt spinning, atomization and DDDR processes. The different types of bonded magnets reviewed include isotropic and anisotropic neodymium-iron-boron, nanocomposites, Sm-Fe interstitial nitrides, Sm-Co and ferrites.

This concise book presents the basic concepts of magnetism and magnetic properties pertinent to permanent magnetic materials. Emphasis is placed on hexaferrite materials for permanent magnet applications, with M-type ferrites as the focal point. The relatively high metallicity of magnetic materials for practical applications imposes limitations for their efficient use. Accordingly, magnetic oxides with ferromagnetic properties emerged as the most widely used magnetic materials for practical applications, owing to their characteristic high resistivity and low eddy current losses, chemical stability, simplicity of production in mass quantities, and other favorable characteristics. An important class of these oxides is the class of hexagonal ferrites developed in the early 1950’s, which dominated the world market of permanent magnet applications since the end of the 1980’s. Among these ferrites, the magnetoplumbite (M-type) hexaferrite, is produced nowadays in large quantities at very competitive low prices, thus providing the permanent magnet market with probably the most cost-effective magnetic material.
