## Description

- description: Iron-based cubic alloy systems opened the door to the development of
    magnetostrictive materials with moderate magnetostriction, low cost, and good
    mechanical properties. At the as-cast state, the grain growth orientation of these
    alloy systems is close to random, which deteriorates magnetostriction. Doping
    with certain elements can tune the growth orientation to enhance magnetostriction.
    However, the driving force for the crystal growth along preferential orientation
    is still not clear. Here in this work, revealed by density functional theory (DFT)
    calculation, Pt doping can tune the crystal growth direction of FeAl along <100>
    crystal direction (same as easy magnetization direction), which can be utilized
    to realize 90° domain-switching and thus magnetostriction is enhanced greatly.
    These are confirmed by experimental results. The magnetostriction increases from
    29 ppm to 80 ppm, representing a 176% enhancement through doping with 0.4 at.%
    Pt. The maze magnetic domain structures, observed by magnetic force microscope,
    are also preferentially <100> oriented and feature stripes. In consideration of
    the similarity between this study and our previous study on FeGa alloy (C. Zhou
    et al., 2020), it can be expected that our methods can be extended to other magnetostrictive
    materials and help develop polycrystals with desired orientations.
