Abstract
Permanent magnets are pervasive in modern industrial societies. They enable conversion of electrical energy to mechanical energy, they underlie microwave communications, and they constitute the active material in data-storage devices. To sustain the evolution of new and improved permanent-magnet materials, an active research enterprise is required. In this paper, the status of modern rare earth-transition metal magnets is outlined, contemporary research directions are summarized, and unresolved issues and research opportunities are enumerated.
