%X The effect of the orientation on the magnetostriction in Fe81Ga19 alloy has been investigated experimentally and theoretically. The Fe81Ga19 001] and 110] oriented crystals were prepared and the magnetostriction was measured under different pre-stress. The saturation magnetostriction of the 001] oriented crystal increases from 170×10-6 to 330×10-6 under the pre-stress from 0 to 50 MPa. The 110] oriented crystal has a saturation magnetostriction from 20×10-6 to 140×10-6 with the compressive pre-stress from 0 to 40 MPa. The magnetostriction of 001] and 110] oriented crystals has been simulated based on the phenomenological theory. The domain rotation path has been determined and the resultant magnetostriction calculated under different pre-stress. The experimental and simulated results both show that the 001] oriented crystal exhibits better magnetostriction than 110] oriented crystal. The enhancement of the saturation magnetostriction by the compressive pre-stress in the 110] oriented crystal is higher than that in the 001] oriented crystal.
