摘要	The Sm0.86Dy0.14Fex (x = 1.85-2.05) magnetostrictive alloys have been prepared with arc-melting and then cast into a copper mold with a diameter of 8 mm. It is found that the magnetostriction (lambda(//) - lambda(perpendicular to)) increases from -900 x 10(-6) for untreated rod alloys to -1200 x 10(-6) for magnetically annealed rod alloys at the magnetic field of 640 kA/m. In the magnetic annealing temperature range of 483-643 K, the magnetostriction value exhibits a peak at 543 K. The variation of magnetostriction and magnetization with magnetic fields has been determined and the mechanism of domains' movements has been discussed. This result is very important to improve the magnetostrictive property of Sm-Dy-Fe rod alloys. (C) 2013 American Institute of Physics.
