Investigation of Crystalline Iron-Platinum Nickel and Amorphous Rare Earth-Iron Alloys for Permanent Magnets.

Abstract

Samarium-cobalt magnets have large-energy products but their cost is relatively high because of the use of expensive Sm and Co. A recent trend has been observed in industry to encourage conservation of cobalt and to find possible substitutes for this strategic material. The purpose of this program was to develop a permanent magnet without the use of cobalt which could be substituted for the AlNiCo commercial magnets. A number of magnetic materials were identified with properties that could be exploited in permanent magnet development.
