Structure and magnetostriction of high Pr/Ce-content(Tb0.2Pr0.8)1-xCexFe1.93 Laves compounds
文献摘要:
The light rare earth Pr/Ce-contained(Tb0.2Pr0.8)1-xCexFe1.93(0≤x≤1.0)intermetallics were arc melted and magnetoelastic properties were investigated.The compounds of x≥0.40 are found to stabilize at ambient pressure in a single Laves phase with MgCu2-type C15 structure,which is attributed to the strong Ce 4f bonding.The mixed-valence behavior,with a support of the deviation from the linear Vegard's law for both lattice parameter a and saturation magnetization Ms,is observed at room tem-perature.The easy magnetization direction(EMD)was determined by the analysis of XRD on both magnetically aligned samples and the(440)splitting,that is,EMD lies toward<111>axis for x≤0.50 rotating to<110>for x=0.60,accompanied with the structural distortion from rhombohedral to orthorhombic.The substitution of Ce for Tb/Pr is conductive to the reduction of magnetocrystalline anisotropy,giving rise to an improvement of the low-field magnetostriction.The excellent magne-toelastic properties can be tailored by the Ce introduction,e.g.,the spontaneous magnetostriction co-efficient λ111 as large as 1150×10-6 for x=0.40,and the low-field induced magnetostriction achieving a high value of λa=180×10-6 at 80 kA/m for x=0.60.The excellent magnetoelastic properties and the combination in high Pr-content with low cost,suggest promising prospects in applications.
