It was estimated that the magnetostriction of PrFe 2 is larger than that of TbFe 2 at 0 K. In this paper, polycrystalline PrF% was prepared by a high-pressure synthesis method. Its structure, magnetic properties and thermal stability were investigated. For a multi-phase specimen, the magnetostriction constant, 3.1i-,~., is 1030× 10 -6, comparable to that of Teffenol-D and might be larger if the single phase PrF% could be obtained. The PrF% compound becomes unstable and decomposes into Pr and Fe above 630 K, so it cannot be obtained by high temperature method under normal atmosphere. © I997 Elsevier Science S.A.
