About resistivity, samples with composition X=4 have larger resistivity. About magnetization, the measured saturation magnetization decrease with increases in Ni for Fe81-xNixGa19 alloys. As to the magnetostrictive part, the magnetostriction value has been decrease when the Nickel increases. In the mechanical properties part, the Young's modulus and shear modulus increases with the magnetic field becomes larger, the comparative hardness found in 0% Ni and 26% Ni has pretty good mechanical properties.
