• FeGa-based alloys are potential candidates in magneto-mechanical transversion applications. It has been demonstrated that doping with certain elements results in the increase in λ100 and modification of the texture, both of which effectively enhance the magnetostriction of FeGa. However, the contribution of each factor is difficult to distinguish because of lacking an effective physical model. In this work, based on the independence of saturation magnetostriction ( λ s) on magnetic domain distribution, a paradigm that combines the orientation distribution function and magnetostriction tensor of single crystals is employed to quantify effects of texture on magnetostriction and predict λ100. Then this paradigm is applied to Ag-doped FeGa and the results reveal that the enhancement of λ100 plays a more crucial role in the enhancement of λ s after Ag doping. Our work clarifies the contribution to magnetostriction enhancement from texture and λ100 in element-doped FeGa alloys, and may help develop more high-performance FeGa alloys.
