The objective of this work, is to develop the technology of high- performance transition metal-rare earth magnets for critical applications. High- performance permanent magnets are defined in this context as those having remanences greater than ten thousand gauss and permeabilities of very nearly unity throughout the second and into the third quadrants of their hysteresis loop. The progress that has been made during the period covered by the report is described under these three major headings. Fundamental studies of the origin of the coercive force in high-anisotropy materials Materials characterization and phase equilibrium studies Alloy development.
