摘要	Using the density functional calculations, we investigated the effect of nanoprecipitation on the magnetostriction of Fe(1-x)Ga(x) alloys. While the B2-like FeGa clusters undergo slight tetragonal distortion, D0(3)-like FeGa clusters remain cubic in the Fe matrix. Moreover, we found that B2-like nanostructures produce negative magnetostriction, whereas D0(3)-like nanostructures give small positive magnetostriction in the hypothetical inhomogeneous structures. Therefore, the formation of nanoscale precipitates cannot be the reason for the extraordinary enhancement of magnetostriction of Fe(1-x)Ga(x) alloys. (C) 2010 American Institute of Physics.
