%X The Fe81Ga19 single crystals were grown in a floating zone melting furnace at a growth rate of 4 mm/h by using a seed crystal. A single crystal was grown by using the seed crystal oriented 5o from the <001> orientation. Pole figure tests were taken at different parts of the single crystal and showed that the start and end parts' axial orientations were 5o and 4o from the <001> orientation, respectively. Another single crystal was grown by using the seed crystal oriented <001> orientation. Magnetostrictive properties along the axis of the crystals λ// were measured for the single crystal, and the saturated magnetostriction λ// up to 0.0324% was achieved under the pre-stress of 60 MPa. Initial magnetization curves were measured in single crystals along <100>, <110> and <111> axis, respectively. From the magnetization curves, magnetocrystalline anisotropy constants of Fe81Ga19 alloys were calculated, and the values of K1 and K2 were 1.3×104 and -2.6×104 J/m3, respectively.
