  Magnetic properties and thermal stability of PrFe2 compound

  摘要：

  It is thought that Pr ions make a large contribution to the magnetocrystalline anisotropy and magnetostriction of Pr-Fe intermetallic compounds. It was estimated that the magnetostriction of PrFe2 is larger than that of TbFe2 at 0 K. In this paper, polycrystalline PrFe2 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, lambda(parallel to)-lambda(perpendicular to) is 1030x10(-6), comparable to that of Terfenol-D and might be larger if the single phase PrFe2 could be obtained. The PrFe2 compound becomes unstable and decomposes into Pr and Fe above 630 K, so it cannot be obtained by high temperature method under normal atmosphere. (C) 1997 Elsevier Science S.A.

  Polycrystalline alloys PrFex (x = 1.5, x = 1.8, x = 1.9, x = 2.0, x = 3.0) have been prepared by arc-melting and subsequent high-pressure synthesis method. Their structure, thermal stability, easy magnetization direction and magnetostriction are investigated. Almost single Laves phase (MgCu2-type) is found in sample with x = 1.9. Samples with x = 2.0, x = 3.0 consist of PrFe1.9 phase with MgCU2-type cubic structure and alpha-Fe phase. The Curie temperature (238 degrees C) and the decomposed temperature (408 degrees C of PrFe1.9 alloys are derived from M-T curves. The easy magnetization direction of PrFel.9 Laves phase lies along [111] axis at room temperature which is verified by Mossbauer spectrum. Furthermore, PrFel.9 alloy shows a large magnetostriction lambda(parallel to) -lambda(perpendicular to) = 1081 x 10(-6) at a magnetic field of 13 kOe. (c) 2006 Elsevier B.V. All rights reserved.
