Main attention of this paper was devoted to studying the effect of solidification texture on microstructure(phase constituents,grain morphology,and magnetic domain structure) of polycrystalline Fe_(82)Ga_(18) sample.The alloy was melted using button arc melting and solidified in water-cooled copper mold.Optical microscope(OM) results confirm the development of large columnar grains in the solidification microstructure.Phase constitution and magnetic domain structures of the sample were studied by X-ray diffraction(XRD) and magnetic force microscopy(MFM).Results show a single-phase solid solution with an A2 structure for the sample which consists of regularly aligned magnetic domains.Although some maze-like subdomains are found in few regions,well-aligned stripe-like domains are predominant patterns in the sample.It demonstrates the high dependence of grain morphology and magnetic domain structure upon a preferred crystallographic direction during solidification.
