Abstract:

The results of a three-year study of attempts to produce magnetically soft materials by mechanical milling show that a major obstacle to the achievement of the desired results of high saturation magnetization with low magnetic anisotropy, using iron-cobalt, is the extreme hardness of the particles after milling. This is the compaction problem that must be solved for the material to be useful for technical applications. The project did result in the establishment of three research facilities that have subsequently led to major new insights into micromagnetics, magnetic random access memory, and the magnetic structure of Fe Al alloys. This project led to additional funding of research at Virginia State University, an Historically Black CollegeUniversity, and has stimulated interest among students in physics research, subsequently leading them to seek advanced degrees in physics.
