Notes:
The growth velocity has a significant effect on the preferred orientation of the directionallysolidified Fe81Ga19 magnetostrictive alloy. Strong 〈100〉 preferred orientation was obtained for avelocity range from 10mm/h to 20mm/h. An excellent magnetostriction λ100 of 294×10-6 wasachieved for the 〈100〉 oriented crystal at a pre-stress of 74.1MPa. Linear and volumemagnetostrictions were investigated in the as-cast Fe81Ga19 alloys with A2 phase by measuring thechange in length along the three-dimensional directions of the samples. Due to the contribution of thevolume magnetostriction, the longitudinal magnetostriction increased from 27 ppm at 0.3 T to 47 ppmat 2.0 T. The volume magnetostriction can be drastically enhanced by doping Ga in Fe
