中文摘要	The anisotropic magnetostriction has been studied in detail for the positive magnetostrictive material of Terfenol-D under two types of magneto mechanical loading. Under the application of the axial compressive stress sigma(parallel to) and the axial magnetic field H-parallel to, the axial negative magnetostriction was observed when H-parallel to increased to coercive field around, which was similar with the butterfly hysteresis in PZT. However, under the application of the axial compressive stress or,, and the transversal magnetic field H-perpendicular to, the "W" shape magnetostriction was observed firstly, which should be taken into consideration to avoid unexpected accidents for practical applications. The anisotropic phenomenon was explained by the domain rotation mechanism, where the demagnetization field effect was considered due to the shape anisotropy of the materials. (C) 2008 Elsevier B.V.
